oo Sprint 7:20 PM Done q4.pdf 1. Glycelysis is a series of chemical reactions Cendergonic and exergonic) by which the cell can obtain ATP, NAD+ plays crucial role in the reactions of glycolysis by Donating electrons to ADP o ake ATP Donating electrons to pyruvate when glucose gets partially oxidized Converting endergonic reactioes to exergonic reactions so that there is an output ed energy to make ATP Accepting electrons from glucose so that glucose gets partially oxidized to pyruvae 2. oxygen is unavailable, predict what happens to the citric acid cycle It continues because none of the reactions in the eitrie acid cyele require oxygen It stops because the supplies of NAD+ and FAD become depleted It stops because ADP levels increase in the absence of oxypen It continues because ATP levels are low, and low ATP activates enrymes of the cycle 3. During oxidative phosphorylation, the production of ATP is endergonic and is directly coupled to what exergonic process? The movement of electrons from high to low potential energy The formation of a chemical bond in ATP The movement of protons from high to low concentration The formation of chemical bonds in water Please refer to your handout from class to wer this question about the oxidative phosphorylation pathway, Cyanide blocks the function of cytochrome a1, and prevents electron transfer to oxygen. What accumulates when cyanide poisoning occurs? Cyt al (reduced form) C FeS2 (exidized fom) ATP C NADI Based on the diagrams below, a photon of 510 nm light will most likely be absorbed byExplanation / Answer
1. d. Accepting electrons from glucose so that the glucose so that the glucose gets partially oxidized to pyruvate
NAD+ and FAD are the electrons carriers, they redealy accept electrons and oxidize the substrate molecules.
2. b. It stops because the supply of NAD+ and FAD become depleted.
Citric acid cycle in the absent of oxygen stops because the supply of NAD+ and FAD become depleted. Though citric acid cycle do not directly use oxygen, it depends on the NAD+ and FAD that are generated by oxidative phosphorylation process.
3. a. the movement of electrons from to low potential energy is an exergonic process.
4. Cyt a1
Cytochrome a1 accumulates in cyanide poisoning because cyanide blocks its turnover.
5. a. carotenoids
6. a. An electron to a chlorophyll (photosynthetic pigments) molecule.
7. b. Sucrose and glucose
