True or false?

(note: the animation has not changed from the original; it's up to you to determine how it would look with the alteration)[Reminder: DCPIP 'steals' electrons from Pq). Over time, more and more molecules of DCPIP would be reduced by electrons taken from plastoquinone (Pq) Water splitting by Photosystem Il would occur at higher levels than if the drug were administered without DCPIP Events in Photosystem I would occur just as they would in the absence of drug and DCPIP

Explanation:

1. Over time more and more molecules of DCPIP would be decreased by electrons taken from plastoquinone (Pq). This statement is true in the sense that DCPIP is an artificial electronic acceptor which is decreased by taking electrons from plastoquinone.

2.) Water splitting by Photosystem II would occur at higher levels than if the drug were administered without DCPIP. This statement is true.

3.)Events in Photosystem I would occur just as they would in the absence of drug and DCPIP. This statement is false because the drug obstructs the electron transport from plastoquinone to cytochrome B. So the events are abnormal because no protein transfer is involved in this mechanism.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
