The sodium-potassium pump does not do which of the following actions?
-Moves sodium molecules against their concentration gradient into the cell
using ATP.
-Moves sodium molecules against their concentration gradient out of the cell
using ATP.
-Maintains the cell's physiological needs by establishing an electrochemical
gradient.
-Moves potassium molecules against their concentration gradient into the cell
using ATP.

Answers

Answer 1

The sodium-potassium pump does not allow the movement of sodium molecules against their concentration gradient into the cell  with the use of ATP molecules.

In sodium-potassium pump, the sodium moves outside the cell whereas potassium moves inside the cell with the help of using ATP molecules. The sodium-potassium pump maintains the gradient of higher concentration of sodium extracellularly means outside the cell and a higher level of potassium intracellularly means inside the cell. This process is done only in the presence of ATP molecules that provides a force for the movement of sodium and potassium so we can conclude that no movement of sodium occur inside the cell in the sodium-potassium pump.

https://brainly.com/question/24347696

Answer 2

Answer: Moves sodium molecules against their concentration gradient INTO the cell using ATP.

Explanation:

The sodium-potassium pump moves sodium molecules against their concentration gradient out of the cell and moves potassium molecules against their concentration gradient into the cell. It also helps to regulate internal physiological needs through gradients. However, it doesn’t move sodium ions into the cell—that occurs through passive transport.

Which of the following shows the correct energy flow during aerobic respiration?
A. Lipids, Glucose, ATP, cells
B. ATP, Glucose, cells
C. Carbohydrates, Glucose, ATP, cells
D. Carbohydrates, Glucose, Lactic acid, ATP

Answers

The correct energy flow during aerobic respiration is ATP, Glucose, and cells. Thus, the correct option is B.

What is Aerobic respiration?

Aerobic respiration may be defined as the process of conversion of glucose into carbon dioxide, water, and energy via the intermediate product of pyruvate in presence of air.

The release of energy in aerobic respiration is found to be greater as compared to anaerobic respiration.

This released energy is immediately used to synthesize a molecule called ATP via glucose that fuels the cells for metabolic activities.

Therefore, the correct option for this question is B.
