We have already talked about another class of chemicals that helps send signals in the body—neurotransmitters. How are neurotr
Darina [25.2K]

Answer:

Similarities: both are chemical messengers, both can have (but don't necessarily have) similar structures (made from amino acids), both can be produced by the central nervous system (hypothalamus produces some hormones), certain molecules can act as both hormones and neurotransmitters (example: norepinephrine).

Differences: neurotransmitters are released by neurons across a synaptic gap, have very short distances to travel, and act very quickly on the neighboring cell. Hormones are released by glands and often have to travel longer distances, which means that they are slower-acting. Also, hormones are typically used for regulation (negative feedback) while neurotransmitters are used for stimulation of a neighboring cell.

Which describes an oxidation reaction that occurs during cellular respiration?
Yuri [45]

Answer: <u>Option 4; Oxygen gains electrons and hydrogen to form water. </u>

Respiration is a process where glucose is used and energy is released stored in this molecule. Oxygen is used during respiration as well and it gains the electrons and hydrogen to form water. And, gain of electrons is an oxidation reaction. So answer is option 4.

Since, oxygen is consumed during respiration, option 1 is incorrect.

Loss of electrons is reduction, so option 2 is also incorrect.

Glucose is used in respiration, thus option 3 is incorrect.
