Describe how the following stages occur in a neuron in terms of ion movement across the cell membrane: resting potential, threshold potential, depolarization, repolarization.

Answers

Answer 1
Answer: We have two surfaces of nerve cell the outer and inner surface

- resting : when the outer layer ion charges more positively than the inner layer - depolarization : we have the counter part of this state
- repolarization : return to the polarization
- hyperpolarization : the inner negative ion charges will be more negative even more than the resting potential

I hope that this is the answer that you were looking for and it has helped you.
Answer 2
Answer:

Answer:

Resting potential is when there are more positively charged ions outside the cell than there are inside the cell, and this is the regular state.

Threshold potential is when there is a triggering event that depolarizes the cell body, where positively charged ions enter the cell body at a rapid rate.

Depolarization is when the membrane potential gets smaller, and the cell begins to equalize itself on the inside and out. Positively charged ions enter the negatively charged axon, resulting in the cell being positively charged.

Repolarization brings the cell back to its resting potential - the ion gates of the cell close, keeping the positively charged ions out, while the potassium gates remain open.

Answers

Answer:What part of the amino acid contributes to the hydrophobic behavior of a region of the polypeptide?":

The hydrophobic behavior of a region of the polypeptide is primarily influenced by the presence of nonpolar amino acids with bulky side chains, such as alanine, valine, leucine, isoleucine, phenylalanine, and tryptophan. These nonpolar side chains do not interact with water molecules and instead fold away from water to minimize contact with the polar environment.

Write the level of glucose in biological organization?

Answer: It’s bigger than black and white

Explanation:

We done have a hell of a year

Final answer:

Glucose is found at different levels of biological organization, serving as an energy source for cellular metabolism, regulated by hormones to maintain homeostasis.

Explanation:

Glucose is a simple sugar, also known as a monosaccharide, with the chemical formula C6H12O6. It is a primary source of energy in living organisms through cellular respiration. Glucose is commonly found in many foods and serves as a crucial energy source for the human body, especially in the form of blood sugar.

The level of glucose in biological organization can be understood at different levels of organization in living organisms. At the molecular level, glucose is a sugar molecule that serves as a source of energy for cellular metabolism. At the cellular level, glucose is broken down through a process called glycolysis to produce ATP, the energy currency of cells. At the organismal level, glucose levels are tightly regulated by hormones such as insulin and glucagon to maintain homeostasis.
