What are 3 stages of cellular respiration?
Summary: the three stages of Aerobic Respiration Carbohydrates are broken down using all three stages of respiration (glycolysis, citric acid cycle and the electron transport chain).
What are the different stages of respiration?
There are four stages: glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation. During glycolysis, glucose molecules (six-carbon molecules) are split into two pyruvates (three-carbon molecules) during a sequence of enzyme-controlled reactions. This occurs in both aerobic and anaerobic respiration.
What happens in each stage of cellular respiration?
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules.
What is the process of cellular respiration?
cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

What is the third step of cellular respiration?
Electron transport and oxidative phosphorylation is the third and final step in aerobic cellular respiration. The electron transport chain is a series of protein complexes and electron carrier molecules found within the mitochondrial membrane in eukaryotic cells. Through a series of reactions, the "high energy" electrons generated in the citric acid cycle are passed to oxygen. In the process, a chemical and electrical gradient is formed across the inner mitochondrial membrane as hydrogen ions are pumped out of the mitochondrial matrix and into the inner membrane space. ATP is ultimately produced by oxidative phosphorylation—the process by which enzymes in the cell oxidize nutrients. The protein ATP synthase uses the energy produced by the electron transport chain for the phosphorylation (adding a phosphate group to a molecule) of ADP to ATP. Most ATP generation occurs during the electron transport chain and oxidative phosphorylation stage of cellular respiration.
Where does cellular respiration occur?
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.
How is ATP produced?

What is the process of converting carbon sugar into acetyl CoA?
The Citric Acid Cycle , also known as the tricarboxylic acid cycle or the Krebs Cycle , begins after the two molecules of the three carbon sugar produced in glycolysis are converted to a slightly different compound (acetyl CoA). It is the process that allows us to use the energy found in carbohydrates , proteins, and fats.
What is the process of converting sugars into energy?
This complex yet efficient metabolic process, called cellular respiration, converts the energy derived from sugars, carbohydrates, fats, and proteins into adenosine triphosphate, or ATP, a high-energy molecule ...
How does glycolysis occur?
Glycolysis occurs when glucose and oxygen are supplied to the cells by the bloodstream, and it takes place in the cell's cytoplasm. Glycolysis can also occur without oxygen, a process called anaerobic respiration, or fermentation. When glycolysis occurs without oxygen, cells make small amounts of ATP. Fermentation also produces lactic acid, which can build up in muscle tissue, causing soreness and a burning sensation.
How does the citric acid cycle produce energy?
Through a series of reactions, the "high energy" electrons generated in the citric acid cycle are passed to oxygen. In the process, a chemical and electrical gradient is formed across the inner mitochondrial membrane as hydrogen ions are pumped out of the mitochondrial matrix and into the inner membrane space.
What are the steps of cellular respiration?
Steps of cellular respiration 1 (Glycolysis): Steps of cellular respiration 2 (Krebs cycle or Citric Acid Cycle): Steps of cellular respiration 3 (Electron Transport Chain): Catabolism of proteins, fats, and carbohydrates in the 3 steps of cellular respiration.
How does cellular respiration help the body?
Cellular respiration plays an important role in releasing the energy to break down glucose to make ATP (Adenosine Triphosphate). Adenosine Triphosphate, also knew as, ATP is an organic compound, which provides energy in living cells in the body. In this process, each molecule of glucose makes 38 molecules of ATP. Here is the equation below:
What is the name of the enzyme that splits glucose into two molecules?
A glucose molecule split by the enzymes and forms into two- molecules of pyruvate as known as pyruvic acid. When the two molecules of pyruvate formed, the energy released four molecules of ATP and the two-electron carriers NADH (Nicotinamide Adenine Dinucleotide + Hydrogen) made.
How many ATPs can glucose produce in cellular respiration?
Glucose plays a vital role in the Glycolysis, the Krebs cycle, ETC (Electron Transport Chain). One molecule of glucose can potentially cause 38 molecules of ATPs from cellular respiration.
What are the results of the Krebs cycle?
As a result, the hydrogen atoms, and the electrons of NADH, and FADH2, that will lead to the Electron Transport Chain for the high energy conditions for cellular respiration. Results of the Krebs cycle are: 4 ATP (contains 2 molecules from Glycolysis) 10 NADH (contains 2 molecules from Glycolysis) 2 FADH2.
What is the process of releasing glucose to make ATP?
Now, you might have a few questions about living things. Living things make use of this energy by a process called cellular respiration. Cellular respiration plays an important role in releasing the energy to break down glucose to make ATP (Adenosine Triphosphate).
What is the name of the enzyme that makes ATP?
ATP Synthase is a type of an enzyme that makes ATP continuously for the reactions and cellular respiration. 10 NADH is of 2 molecules from Glycolysis, 8 molecules from the Krebs cycle. 2FADH2 is accepted from the Krebs cycle.
Where does cellular respiration occur?
Answer: The first stage of cellular respiration occurs in the cytoplasm. This is where glucose is broken down into smaller molecules. A small amount of energy is also released. The second stage occurs in the mitochondrion. This is where the small molecules combine with oxygen to produce water, carbon dioxide, and a large amount of energy.
Where does the second stage of the cellular cycle occur?
The second stage occurs in the mitochondrion. This is where the small molecules combine with oxygen to produce water, carbon dioxide, and a large amount of energy. Explanation: taffy927x2 and 346 more users found this answer helpful. heart outlined.
