Which of the three stages of aerobic respiration makes the most ATP?

The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS) present in mitochondria.

Where do the three major steps of aerobic cellular respiration take place for eukaryotes?

The three main stages of cellular respiration (aerobic) would include Glycolysis in the cytoplasm the Kreb’s Cycle in the Mitochondrial Matrix and the Electron Transport Chain in the Mitochondrial Membrane.

Where do the three major steps take place for eukaryotes?

Cellular respiration occurs in both eukaryotic and prokaryotic cells with most reactions taking place in the cytoplasm of prokaryotes and in the mitochondria of eukaryotes. There are three main stages of cellular respiration: glycolysis the citric acid cycle and electron transport/oxidative phosphorylation.May 6 2019

What are the three products of cellular respiration?

Cellular respiration is this process in which oxygen and glucose are used to create ATP carbon dioxide and water. ATP carbon dioxide and water are all products of this process because they are what is created.

What are the 2 stages of aerobic respiration quizlet?

The Stages of Aerobic Respiration
  • Glycolysis.
  • The Krebs Cycle.
  • The Electron Transport System.

What are the three phases of aerobic cellular respiration and where in the cell does each of these occur quizlet?

The 3 phases of cellular respiration are Glycolysis the Krebs Cycle and the Electron Transport Chain. Where in the cell does the glycolysis part of cellular respiration occur? Glycolysis occurs in the cytoplasm of the cell.

What are the 4 major steps in cellular respiration?

The stages of cellular respiration include glycolysis pyruvate oxidation the citric acid or Krebs cycle and oxidative phosphorylation.

What is the first step involved in respiration?

The first step in respiration is to perform breathing which involves inhalation of air to get the oxygen followed by exhalation of carbon dioxide. This step is further carried forward through the diffusion of gases into the blood and out of the blood. The freshly diffused oxygen is then transported to the tissues.

What are the 3 steps of cellular respiration and where does each occur?

Cellular respiration is the process in which cells break down glucose release the stored energy and use it to make ATP. The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages: glycolysis the Krebs cycle and electron transport.

What are the 3 main steps of the electron transport chain?

The three main steps in the electron transport chain are:
  • Generation of a proton gradient across the mitochondrial membrane. Proton accumulation occurs in the intermembrane space of mitochondria.
  • Reduction of molecular oxygen and formation of water. …
  • ATP synthesis by chemiosmosis.

Where do each of the 3 steps in cellular respiration occur in a eukaryotic cell list the part of the cell )?

Cellular respiration takes place in both the cytosol and mitochondria of cells. Glycolysis takes place in the cytosol whereas pyruvate oxidation the Krebs cycle and oxidative phosphorylation occur in the mitochondrion.

What is aerobic respiration anaerobic respiration?

Summary. Cellular respiration always begins with glycolysis which can occur either in the absence or presence of oxygen. Cellular respiration that proceeds in the absence of oxygen is anaerobic respiration. Cellular respiration that proceeds in the presence of oxygen is aerobic respiration.

What are the three main biochemical pathways of cellular respiration?

Cellular respiration is a collection of three unique metabolic pathways: glycolysis the citric acid cycle and the electron transport chain.

What is the aerobic respiration?

Aerobic respiration is the process of producing cellular energy involving oxygen. Cells break down food in the mitochondria in a long multistep process that produces roughly 36 ATP. The first step in is glycolysis the second is the citric acid cycle and the third is the electron transport system.

What are the three main products of cellular respiration quizlet?

The three products of cellular respiration are ATP energy carbon dioxide and water.

What are the products of each stage of aerobic cellular respiration?

Carbohydrates are broken down using all three stages of respiration (glycolysis citric acid cycle and the electron transport chain).

Summary: the three stages of Aerobic Respiration.
Glycolysis Citric acid cycle Electron transport chain

What is the second major stage of aerobic respiration?

The second stage of cellular respiration the Krebs cycle takes place in the matrix. The third stage electron transport takes place on the inner membrane.

What are two stages of aerobic?

The different stages of aerobic respiration are:
  • Glycolysis.
  • Formation of acetyl coenzyme A.
  • Citric acid cycle.
  • Electron Transport Chain.

What happens in the 2 stages of anaerobic respiration?

In the glycolysis the glucose molecule breaks down into two three carbon compound pyruvic acid. In the second stage the pyruvic acid undergoes incomplte oxidation i.e. fermentation. The incompplete oxidation of the pyruvic acid yields ethano or lactic acid.

What are the three processes of cellular respiration and how many ATP’s are made at each process?

How much ATP is produced in all three stages? Glycolysis produces 2 ATP molecules and the Krebs cycle produces 2 more. Electron transport begins with several molecules of NADH and FADH2 from the Krebs cycle and transfers their energy into as many as 34 more ATP molecules.

What are the 4 stages of cellular respiration and where do they occur?

The cellular respiration process includes four basic stages or steps: Glycolysis which occurs in all organisms prokaryotic and eukaryotic the bridge reaction which stets the stage for aerobic respiration and the Krebs cycle and the electron transport chain oxygen-dependent pathways that occur in sequence in the …

What are the two major steps of respiration?

The process of physiological respiration includes two major parts: external respiration and internal respiration. External respiration also known as breathing involves both bringing air into the lungs (inhalation) and releasing air to the atmosphere (exhalation).

What are two steps involved in respiration?

The steps involved in respiration are as follows:
  • Pulmonary ventilation or breathing through which atmospheric air is drawn in and carbon dioxide-rich air is given out.
  • Diffusion of gases across the alveolar membrane.
  • Gaseous transport by the blood.
  • Diffusion of carbon dioxide and oxygen between tissues and blood.

How many steps are involve in respiration

Breathing involves two stages : inspiration during which atmospheric air is drawn in and expiration by which the alveolar air is released out.

What are the three major minimum components of an electron transfer system?

The electron transport chain is also called the Cytochrome oxidase system or as the Respiratory chain. The components of the chain include FMN Fe–S centers coenzyme Q and a series of cytochromes (b c1 c and aa3).

What are the 4 steps of the electron transport chain?

The key steps of this process shown in simplified form in the diagram above include:
  • Delivery of electrons by NADH and FADH 2​start subscript 2 end subscript. …
  • Electron transfer and proton pumping. …
  • Splitting of oxygen to form water. …
  • Gradient-driven synthesis of ATP.

What are the major events of the electron transport chain?

The events of the electron transport chain involve NADH and FADH which act as electron transporters as they flow through the inner membrane space. In complex I electrons are passed from NADH to the electron transport chain where they flow through the remaining complexes. NADH is oxidized to NAD in this process.

What are the stages of aerobic and anaerobic respiration?

During aerobic cellular respiration glucose reacts with oxygen forming ATP that can be used by the cell.

Aerobic vs anaerobic respiration.
Aerobic Anaerobic
Stages Glycolysis (anaerobic) Krebs cycle oxidative phosphorylation Glycolysis fermentation

What are 3 differences between aerobic and anaerobic respiration?

Anaerobic respiration happens in human muscle cells (eukaryotes) bacteria yeast (prokaryotes) etc.
Aerobic Respiration Anaerobic Respiration
Glucose breaks down or complete oxidation into carbon dioxide and water. Glucose breaks down into ethyl alcohol carbon dioxide and energy.

Which of the following is the first step of both anaerobic and aerobic respiration?

The first step of aerobic respiration ia glycolysis or also called as EMP pathway or common pathway. It is known so because it’s first step called glycolysis is common to both aerobic and anaerobic modes of respiration.
