What are the three main stages of aerobic cellular respiration quizlet?
Aerobic ("oxygen-using") respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.
What are the aerobic stages of respiration?
Aerobic respiration is a series of enzyme-controlled reactions that release the energy stored up in carbohydrates and lipids during photosynthesis and make it available to living organisms. There are four stages: glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation.
What are the 3 stages of cellular respiration and where do they occur?
1 Answer. BRIAN M. 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.
What are the names of the 3 stages of cellular respiration?
The three stages of cellular respiration are glycolysis, Krebs cycle and oxidative phosphorylation by the electron transport system (ETS).
What are the three main reactions in cellular respiration quizlet?
The reactions of cellular respiration can be grouped into three stages: glycolysis, the Krebs Cycle, and electron transport.
What is the first step of aerobic cellular respiration?
Glycolysis Glycolysis, the first step of cellular respiration, occurs in the cytoplasm of your cells. During this process, a glucose molecule is broken down into two molecules of pyruvate (pyruvic acid).
What is the first step of aerobic respiration?
The first step in both anaerobic and aerobic respiration is called glycolysis. This is the process of taking one glucose (sugar) molecule and breaking it down into pyruvate and energy (2 ATP).
What are the stages of cellular respiration in order?
The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
Which of the following puts the stages of aerobic respiration in the correct order?
So, the correct answer is 'Glycolysis, Krebs cycle, Electron transport chain'.
What is the correct order of stages of cellular respiration?
The reactions of cellular respiration can be grouped into three stages: glycolysis (stage 1), the Krebs cycle, also called the citric acid cycle (stage 2), and electron transport (stage 3).
What is the correct order for steps of aerobic cellular respiration from start to finish?
Aerobic respiration involves four stages: glycolysis, a transition reaction that forms acetyl coenzyme A, the citric acid (Krebs) cycle, and an electron transport chain and chemiosmosis.
What is the first stage of cellular respiration?
Glycolysis Glycolysis, the first step of cellular respiration, occurs in the cytoplasm of your cells. During this process, a glucose molecule is broken down into two molecules of pyruvate (pyruvic acid).
What is the second step of aerobic respiration?
The second step in aerobic respiration is the formation of acetyl coenzyme A. In this process, pyruvate is oxidized in the mitochondria and 2-carbon acetyl group is produced.
What is the third stage of cellular respiration?
The reactions of cellular respiration can be grouped into three stages: glycolysis (stage 1), the Krebs cycle, also called the citric acid cycle (stage 2), and electron transport (stage 3).
What is the final stage of aerobic respiration?
Oxidative phosphorylation is the final stage of aerobic cellular respiration. There are two substages of oxidative phosphorylation, Electron transport chain and Chemiosmosis. In these stages, energy from NADH and FADH2, which result from the previous stages of cellular respiration, is used to create ATP. Figure 5.9.
What is the last stage of aerobic cellular respiration?
Oxidative phosphorylation Oxidative phosphorylation is the final stage of aerobic cellular respiration. There are two substages of oxidative phosphorylation, Electron transport chain and Chemiosmosis. In these stages, energy from NADH and FADH2, which result from the previous stages of cellular respiration, is used to create ATP. Figure 5.9.
What are the 3 steps to energy exchange from ADP to ATP?
Quiz
- ATP consists of adenosine and two inorganic phosphates.
- When ADP is broken down into ATP, energy is released.
- ATP is synthesized by the cell through cell respiration.
- In the absence of oxygen, respiration occurs in the following steps: Glycolysis, Kreb's Cycle, and Cytochrome System.
What are the stages of anaerobic respiration?
Anaerobic respiration has two stages: glycolysis and fermentation. Glycolysis in anaerobic respiration is similar to that in aerobic respiration. A 6-carbon glucose molecule of glucose still splits into two 3-carbon pyruvate molecules. Fermentation then occurs following glycolysis.
What is the second stage of cellular respiration?
Krebs Cycle The second stage of cellular respiration is the 'Krebs Cycle'. This is a catabolic reaction that occurs within the cells. In cells, the energy is produced and stored in the form of ATP. The 'Krebs Cycle' is also known as the TCA cycle or citric acid cycle.
What are the 4 stages of aerobic respiration of glucose?
Aerobic respiration has four stages: Glycolysis, formation of acetyl coenzyme A, the citric acid cycle, and the electron transport chain.
What are the general steps of the ATP ADP cycle in aerobic cellular respiration?
The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
What happens during anaerobic cellular respiration?
Answer: During anaerobic cellular respiration, glucose is broken down without oxygen. The chemical reaction transfers glucose energy to the cell. In fermentation, instead of carbon dioxide and water, lactic acid is produced which can lead to painful muscle cramps.
What are the three stages of anaerobic?
ADVERTISEMENTS: Anaerobic digestion is accomplished in three stages, solubilisation, acidogenesis and methanogenesis.
Which of the phases are aerobic and which are anaerobic?
There are two types of cellular respiration: aerobic and anaerobic. One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic). Both begin with glycolysis – the splitting of glucose. Glycolysis is an anaerobic process – it does not need oxygen to proceed.
What is the first stage of cellular respiration called?
Glycolysis Glycolysis, the first step of cellular respiration, occurs in the cytoplasm of your cells. During this process, a glucose molecule is broken down into two molecules of pyruvate (pyruvic acid).
What are the 4 stages of cellular respiration?
The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
Which of the following steps or processes in aerobic respiration include the production of carbon dioxide?
Which of the following steps or processes in aerobic respiration include the production of carbon dioxide? In step 4 of glycolysis, a six-carbon sugar (fructose 1,6-bisphosphate) is cleaved to produce two three-carbon molecules (dihydroxyacetone phosphate and glyceraldehyde 3-phosphate).
What are the steps of aerobic and anaerobic respiration?
In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts. The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation.
What are the 2 stages of anaerobic respiration?
Anaerobic respiration has two stages: glycolysis and fermentation. Glycolysis in anaerobic respiration is similar to that in aerobic respiration. A 6-carbon glucose molecule of glucose still splits into two 3-carbon pyruvate molecules. Fermentation then occurs following glycolysis.

This process occurs in three stages: glycolysis , the Krebs cycle , and electron transport .
