Question

» Discuss the 2 ways in which animal cells make ATP (i.e. what is the difference between direct and indirect ATP production?) » Describe the 3 stages via which food molecules are broken down, explaining where each stage takes place in eukaryotes & prokaryotes. · Describe the overall net products of glycolysis · Explain why ATP is used during the early stages of glycolysis (i.e. for what purpose,) » Discuss the purpose of fermentation and identify the products of fermentation in muscle and yeast cells, paying special attention to the redox reactions involved (i.e. reduction of pyruvate, oxidation of NADH to NAD+)

Explanation / Answer

ATP can be produced in two ways :- direct (substrate level phosphorylation )without the use of electron transport chain .they are directly produced by energy released by reshuffling of bond.

Indirect :- which uses the electron transport chain and energy is produced by the proton motive force .

3 stages for carbohydrate breakdown:-

Glycolysis :- occur in cytoplasm of both pro and eukaryote

Link reaction :- occur in cytoplasm in pro and mitochondrial matrix in eukaryote

Kreb cycle :- same as above

Glycolysis :- end product is 2 pyruvate ,2 NET ATP,2 NADH+H

In early stages of glycolysis ATP is used for :-

Conversion of glucose to glucose 6 phosphate

And fructose 6 po4 to fructose 1,6 bisphosphate
