Stages of aerobic cellular respiration

Answer 1

There are 3 processes in aerobic respiration. Glycolysis, Kreb's cycle, and electron transport chain.

A very, very simply, the equation for all those processes is Glucose + Oxygen = Energy + Carbon Dioxide + Water.

But I will describe all these steps a little more detailed for you:

Glycolysis:

1- one molecule of glucose is converted into pyruvate

2- pyruvate is converted into acetyl CoA and CO2

3- the acetyl-CoA enters the citric acid cycle (Kreb's Cycle)

4- 2 ATP molecules, 2 water molecules, and 2 NADH molecules are produced.

Kreb's Cycle:

5- Acetyl CoA is converted into citrate which then goes through a serious of chemical transformations, losing 2 carboxyl groups as CO2 (it is converted back to acetyl CoA by losing the 2 CO2 molecules which helps the production of citric acid)

6- citric acid is broken down and makes 2 molecules of CO2

7- After 2 complete cycles of the Kreb's cycle, 6 NADH molecules, 2 FADAH2 molecules, 2 ATP molecules, and 4 CO2 molecules are produced.

The Electron Transport Chain:

8- H+ electrons from molecules produced in previous steps (H+ removed from NADH, making it NAD+)

9- the H+ are combined with O2 molecules through different membrance transports and the electrical potential between all chemicals is used to generate ATP from ADP+phosphate

10- 32-34 molecules of ATP are produced

Overall, 38 molecules of ATP are generated for every molecule of glucose in the aerobic respiration steps.

Hope this helps. Sorry if I was unclear at any point.

Answer 2

Respiration is what allows or enables Metabolism to Occur.

Respiration cannot take place without fuel for combustion and Oxygen [di-atomic] molecules to provide the combust.

With O2 freely available the first stage is complete. The next critical phase is the acquisition and processing of Foodstuffs; and this provides biochemicals that are used as 'input' for Cellular respiration biochemical processes that provide [generate], primarily, Atp that is used to 'fuel' all Biochemical reactions.

Answer 3

Aerobic cellular respiration consists of four main stages: glycolysis, pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation. These stages involve the breakdown of glucose to produce ATP, which is the cell's primary energy source. Aerobic respiration occurs in the presence of oxygen and is more efficient than anaerobic respiration.

Answer 4

Glycolysis -----> citric acid cycle (aka Krebs cycle) -----> oxidative phosphorylation via the electron transport chain and chemiosmosis
