Learn About Cellular Respiration 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. In aerobic respiration, oxygen is essential for ATP production. In this process, sugar (in the form of glucose) is oxidized (chemically combined with oxygen) to yield carbon dioxide, water, and ATP. The chemical equation for aerobic cellular respiration is C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O + ~38 ATP.

Cellular Respiration Through the first two steps of cellular respiration there is a net gain of 4 ATP. Although the Krebs cycle doesn’t provide much energy, it does yield several molecules of NADH and FADH 2. These two molecules will be the key to producing many more ATPs in the third step of cellular respiration, the electron transport chain.

CHAPTER 4 BIOLOGY The overall process of cellular respiration converts sugar into ATP using oxygen. Glycolysis splits glucose and when oxygen is present the products of glycolysis are used in cellular respiration. The Krebs cycle transfers energy to the electron transport chain, which produces most of the ATP in eukaryotic cells.

Cellular Respiration Fermentation releases CO 2, but does not make any ATP – all ATP during anaerobic respiration is produced during glycolysis. Since glycolysis produces 2 ATP, anaerobic respiration yields 2 ATP for every molecule of glucose. Both glycolysis and fermentation take place within the cytosol/cytoplasm of a cell. In fact, the entire process of anaerobic respiration takes place in the cytosol.

Chapter 12 Nutrients & metabolism Cellular respiration takes place in the organelles called mitochondria. The mitochondria take in glucose, a type of sugar, and change it in the presence of oxygen into an energy-rich molecule called ATP, or adenosine triphosphate. For every molecule of glucose, 36 molecules of ATP are made.

Campbell Biology: Ninth Edition - Chapter 9: Cellular Respiration and Fermentation Flashcards Most of the ATP produced in cellular respiration come from oxidative phosphorylation, in which the energy released from redox reactions in an electron transport chain is used to produce ATP. In substrate level phosphorylation, an enzyme directly transfers a phosphate group to ADP from an intermediate substrate. All ATP production in glycolysis occurs by substrate-level phosphorylation, this form of ATP production also occurs at one step in the citric acid cycle.

What is the first stage of cellular respiration? Answers. Relevance. Rating Newest Oldest. Best Answer: The stages are: Glycolysis, Krebs Cycle, Electron Chain Transport the first stage is Glycolysis, which is the breaking up of glucose a 6 carbon sugar into two 3 carbon molecules called Pyruvate.he three carbon sugar, or Pyruvate, is then broken up into a two carbon molecule called Acetyl CoA, this molecule enters the Krebs Cycle where carbons are added and taken off to create energy(known as ATP), and last is the electron chain transport.

- Aerobic respiration creates the most ATP since oxidative phosphorylation is able to occur. Anaerobic respiration occurs if there is no oxygen present and creates less ATP. So in a nutshell, the main difference is whether or not oxygen is present. Aerobic with oxygen, anaerobic without oxygen.

Glycolysis Krebs Cycle. Electron Transport Chain. Glycolysis is the first stage of cellular respiration, it occurs within the cytoplasm of the cell, it involves the splitting of a sugar (hence the name: glycolysis). The best sugar to use in glycolysis is glucose, but other sugars can be used instead. The point of glycolysis is to convert a single molecule of whatever sugar is at hand into 2 pyruvate molecules.

photosynthesis/cell respiration First stage of cellular respiration, glucose is broken down to pyruvate during glycolysis. Glycolysis is an anaerobic process, and it results in a net gain of 2 ATP molecules. Second stage of cellular respiration, pyruvate either passes through the Krebs cycle or undergoes fermentation.

Cellular Respiration Glycolysis is the first step in cellular respiration for both anaerobic and aerobic processes. Glycolysis takes place in the cytosol of a cell. In the cytosol we convert 1 molecule of glucose into 2 molecules of pyruvate.Of course glucose can’t be converted into pyruvate without a little bit of help. This conversion requires 2 NAD + and some energy, in the form of 2 ATP.ermentation releases CO 2, but does not make any ATP – all ATP during anaerobic respiration is produced during glycolysis. Since glycolysis produces 2 ATP, anaerobic respiration yields 2 ATP for every molecule of glucose. Both glycolysis and fermentation take place within the cytosol/cytoplasm of a cell.
