Answer:
genes
Explanation: I know this because genes make up chromosomes and those make up our dna.
hope this helps!!!
Answer:
Red blood cells
Explanation:
They transport Oxygen throughout the body.
Light reactions happens in the thylakoid membrane, and the calvin cycle happens in the stroma. What happens to water molecules in the light reactions? It's broken apart and the electrons go to photosystem II. ... Then they pump H+ into the thylakoids, and are used to make ATP out of ADP.
Answer:
I think it's hydrogen and carbon atoms
Answer:
B. recycle NADH back to NAD+
Explanation:
Both respiration and fermentation share a common pathway, that is glycolysis. The redox reactions of glycolysis use NAD+ as an electron acceptor and NADH is formed. To continue the process of respiration and fermentation, oxidation of NADH into NAD+ is required so that NAD+ can serve as an electron acceptor for glycolytic reactions.
Aerobic respiration oxidizes NADH into NAD+ by transferring its electrons to the terminal electron acceptor, the molecular oxygen. On the other hand, fermentation oxidizes NADH through the formation of lactic acid or ethanol from pyruvate.
