Question:

What is the difference between the endocrine system and the nervous system?

Inactive
Julie Y.
Answer:

Both systems act as messaging systems in the body, just through different methods. The nervous system uses electrical signaling, through nerve impulses, to communicate from one neuron to the next or from a neuron to a tissue or organ. The endocrine system uses chemical signaling, through hormones, to communicate to various tissues and organs throughout the body via the bloodstream.

Question:

What is the role of NAD+ in cellular respiration?

Inactive
Julie Y.
Answer:

NAD+ acts as an electron carrier. As glucose is broken down into pyruvate, high energy electrons are created that are needed later on in cellular respiration, during the electron transport chain. NAD+ is used as a carrier to "pick up" the electrons during glucose breakdown (making NADH) and "drop off" the electrons in the mitochondria for the electron transport chain (turning back into NAD+)

Question:

What is the visible difference between a monocyte and a neutrophil?

Answer:

A monocyte is an agranulocyte, meaning it lacks granules. Monocytes have a large nucleus that is shaped somewhat like a pacman. Neutrophils, in contrast, are granulocytes, meaning they contain granules in the cytoplasm. Neutrophils also have a multi-lobed nucleus that resembles a chain of sausage links.
