*The key function of each of the two photosystems is to absorb light and convert the energy of the absorbed light into redox energy, which drives electron transport.
In PS II (the first photosystem in the sequence), P680 is oxidized (which in turn oxidizes water), and the PS II primary electron acceptor is reduced (which in turn reduces the electron transport chain between the photosystems).
In PS I, the PS I primary electron acceptor is reduced (which in turn reduces other compounds that ultimately reduce NADP+ to NADPH), and P700 is oxidized (which in turn oxidizes the electron transport chain between the photosystems).
If we dont have enzymes then we would become malnourished as our body wouldnt be able to absorb the nutrients. Enzymes work in digestion to break down the food we eat
I am assuming you would recommend a specialist.
Answer: Step 7
Question: Refer to this portion of a dichotomous key for fish identification to answer the question. 1. (a) Has a single dorsal fin ® 5 (b) Has a double dorsal fin ® 2 5. (a) Has small fin on back near tail ® 6 (b) Has no fin on back near tail ® 7 6. (a) Has barbs near the mouth ® Catfish (b) Does not have barbs near the mouth ® 10 What is the next step to complete to identify a fish that has a single dorsal fin, no fin on the back near the tail, and no barbs near the mouth? step 2 step 5 step 7 step 10
