When NAD+ becomes NADH, it is being reduced.
NAD+ is a coenzyme that is involved in many metabolic reactions. It is a dinucleotide, meaning that it is made up of two nucleotides. The nucleotides are nicotinamide adenine dinucleotide (NAD) and adenosine diphosphate (ADP).
NAD+ is oxidized when it loses an electron. This leaves the nicotinamide ring with an extra hydrogen atom, which gives NADH its name. NADH is a reduced form of NAD+.
The reduction of NAD+ is a necessary step in many metabolic reactions. For example, NADH is used in glycolysis, the process by which cells break down glucose to produce energy. NADH is also used in the Krebs cycle, the process by which cells break down carbohydrates, proteins, and fats to produce energy.

NAD+ accepts a hydrogen ion (H+) and two electrons (2e−), as it becomes reduced to NADH + H+. The NADH moves to the electron transport chain and donates a pair of electrons (becomes oxidized) to the first compound in the chain.

D)
circulatory; respiratory
Answer: The correct answer for the fill in the blank is A) Circulatory, immune.
Circulatory system also called cardiovascular system is a vast network of organs and vessels that allow the circulation of blood so as to transport nutrients, oxygen, other gases, and hormones to different parts of the body.
Blood contains different cells like white blood cells, red blood cells, platelets.
White blood cells ( also called leukocytes) work closely with immune system. They provide defense against pathogen ( disease causing organisms) through various ways ( like ingesting foreign material, producing antibodies to clear the antigens). By doing so, they protect us from infection and disease.
should the labels be?
Zoe'svoluntary action of choosing to move her leg out of the way is labeled as point D. Point B is the one from which signal travels down spinal cord to skeletalmuscle. Zoe uses muscle to move leg out of the way from point C.
Voluntaryaction occurs when an action is performed with the involvement of thoughts.
Voluntary actions are usually being controlled by brain. These are the actions that are takes consciously which is done by coordination of brain and spinal cord.
In the given scenario, Point D represents Zoe's voluntary action of moving her leg out of the way. Point B is where the signal travels down the spinal cord to the skeletal muscle. Zoe uses muscle to move her leg away from point C.
Thus, the answer is pointD.

Answer:
Because this action is a voluntary action, it starts in the brain. Here are the steps:
D: Zoe chooses to move her leg into a different position.
B: Signal travels down spinal cord to skeletal muscle.
C: Zoe uses muscle to move leg out of the way.
Point A is not used in this sequence of steps.
