Question
harry was very thirsty he accidently drank a poison named ccdd to quench his thirst .now he is feeling exausted and tired he decided to lay down since you have studied cellular respiration in biology class harry is hoping you are able to determine where the problem is.
the facts at cellular and molecular level
oxygen present
only produce 4ATP molecule per molecule of glucose
pyruvate is present in cytosol and acetyl coa is present in mitochondria
Nadh and nad+ are normal levels
Fad and Fadh2 are normal level
A. where in the cellular respiration does ccdd block
how do you know support answer with evidence for full credit
Explanation / Answer
human cells use glucose as primary source of energy as follows: glycolysis->citric acid cycle-> electron transport chain
1. glycolysis: glucose is broken into 2 pyruvate molecules
2. pyruvate molecules go to mitochondrea where they go through citrcic acid cycle (first acetyl co enxyme A attaches in it)
3. first 2 steps create NAD H and citric acid cycle FAD H2 wich transfers the H+ in mitochondrea to electrontransport chain.where H are on other side of the inner layer and they haveto push through a protein complex called ATPsyntace wich creates ATP from the H gradent ( gradent = difference between membraces sides). this need oxygen.
ATP:primary usable energy source
in glycolysis : 2
citric acid cycle : 2
electron transport chain = about 28
"the facts at cellular and molecular level

pyruvate is present in cytosol and acetyl coa is present in mitochondria

Fad and Fadh2 are normal level"
We can say first 2 steps work perfectly well ( 4 ATP together and NADH FADH and acetyl CoA are normal)
so the problem lies in the energy transport chain which is responsible of most ATP prodused
( if need more info, just comment,:))
