Answer: The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
Answer:
Option b) Hydrophobic interactions between phe106 and ile108 of one monomer and ile272 and leu273 of the other monomer. Ionic bonds between arg96 and arg103 of one monomer and glu300 and glu304 of the other monomer.
Explanation:
In the structure, there are ionic hydrogen bonds and salt bridges between the 42, R221, and D24. These interactions have a dynamic impact on the activity and structural stability of the protein nature.
The hydrophobic interactions at the interfaces also contribute in the stabilization of the protein structure.
Answer:
D. oxygen is the final electron acceptor.
Explanation:
Oxygen serves as the final electron acceptor in aerobic cellular respiration. The whole pathway includes glycolysis, Kreb's cycle, and oxidative phosphorylation.
Oxidation of NADH and FADH2 formed during glycolysis and Kreb's cycle through electron transport chain during oxidative phosphorylation includes molecular oxygen as the terminal electron acceptor.
The proton motive force generated during the electron transfer from NADH and FADH2 to oxygen gas drives phosphorylation of a large number of ADPs into ATPs.
I do not get it can you explain any better
