Answer:
a. is converted to NAD+ by an enzyme called dehydrogenase
Explanation:
The electron transport chain of cellular respiration is the final step that oxidized NADH and FADH2. These reducing powers are formed during glycolysis and Kreb's cycle. Complex I of the electron transport chain present in the inner mitochondria membrane is NADH dehydrogenase. This protein complex accepts electrons from NADH and oxidizes it into NAD+. NADH dehydrogenase couples oxidation of NADH with the pumping of proton towards the intermembrane space.
First off, we need to understand that osmosis is typically used with the example of water---
To understand that, osmosis is taking water from a high concentration to a low concentration to make the membrane equal to one another .
Imagine you have a pea, and the pea is about to explode of water. And you have another pea that's shriveled up. You would take some of the exploding water's pea into the shriveled one, therefore making it equal. (Thats my example I like to use!)
I hope this helped!
Theres a character minimum smh but i think its d pls check though g00gle is fr33
