How many molecules of CO2 are in aerobic respiration?

Carbon atoms are removed from the organic molecule (glucose) to form carbon dioxide. Aerobic respiration involves the complete combustion of glucose (6C) – so six CO2 molecules are produced.

How many CO2 molecules are produced per glucose in the Krebs cycle?

Two carbon dioxide molecules
Two carbon atoms come into the citric acid cycle from each acetyl group, representing four out of the six carbons of one glucose molecule. Two carbon dioxide molecules are released on each turn of the cycle; however, these do not necessarily contain the most recently-added carbon atoms.

How many CO2 molecules are produced per glucose in cellular respiration?

The process of cellular respiration involves many different steps (reactions) to break down glucose using oxygen to produce carbon dioxide, water and energy in the form of ATP. The 6 carbon atoms present in a glucose molecule make it possible to form 6 carbon dioxide molecules.

How many molecules of CO2 can your body make from one molecule of glucose?

The overall chemical reaction for cellular respiration is one molecule of glucose (C6H12O6) and six molecules of oxygen (O2) yields six molecules of carbon dioxide (CO2) and six molecules of water (H2O).

What are the 4 stages of aerobic 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.

How many ATP molecules does aerobic respiration produce per glucose?

Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).

How many molecules of carbon dioxide are used for every molecule of glucose that is produced by photosynthesis?

6 molecules
For each molecule of glucose produced: 6 water water molecules are oxidized, and become the source of electrons for carbon dioxide reduction. 6 molecules of carbon dioxide are required, one for each carbon atom in glucose.

Is cellular respiration 3 or 4 steps?

Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. Glycolysis is an anaerobic process. The other two stages are aerobic processes. The products of cellular respiration are needed for photosynthesis, and vice versa.
