Glucose is completely converted to CO2, energy is used to produce ATP. What is this process? ( more inside)?

Question

Okay, I have this huge question I need answered for biology. I would really appriecate anyone's answers and help to understanding this problem.

Indiviuals on low-fat, low-protein diets obtain the bulk of their energy from carbohydrates. Complex carbohydrates such as starch and disaccharides such as sucrose are first broken down into glucose. Through a series of metabolic reactions and pathways, the glucose is completely converted to CO2, and the energy it contains is used to produce ATP. Describe this process in detail, using schematic diagrams to explain your answer.

Answer 1

Glucose catabolism
Glucose will be oxidised by all tissues to synthesise ATP. The first pathway which begins the complete oxidation of glucose is called glycolysis.
Glycolysis
This pathway cleaves the six carbon glucose molecule (C6H12O6) into two molecules of the three carbon compound pyruvate (C3H3O3-). This oxidation is coupled to the nett production of two molecules of ATP/glucose.
The diagram below shows an outline of glycolysis. The full set of reactions and structures can be found in any biochemistry textbook.
One oxidation reaction occurs in the latter part of the pathway. It uses NAD as the electron acceptor. This cofactor is present only in limited amounts and once reduced to NADH, as in this reaction, it must be re-oxidised to NAD to permit continuation of the pathway.

pyruvate is transported inside mitochondria and oxidised to a compound called acetyl coenzyme A (abbreviated to "acetyl CoA").
This is an oxidation reaction and uses NAD as an electron acceptor.

By a further series of reactions collectively called the citric acid cycle, acetyl CoA is oxidised ultimately to CO2. These reactions are coupled to a process known as the electron transport chain which has the role of harnessing chemical bond energy from a series of oxidation/reduction reactions to the synthesis of ATP and simultaneously re-oxidising NADH to NAD.

Answer 2

Glycolysis ---> Kreb's Cycle ---> Electron Transport Chain in the Mitochondria (Oxidative Phosphorylation)

Answer 3

carbon dioxide will diffuse out of the air into the leaf and water will travel from the rot to the leave the chlorophyll on the plant will trap sunlight energy, this sunlight energy is used to split water molecules into hydrogen and oxygen, the hydrogen will combine with carbon dioxide to form glucose and the oxygen will diffuse out of the leaf into the atmousphere, glucose is very reactive so it is transported in the plant as sucrose and then it is stored as starch
