Answer:
The correct option is: e. molecules move across the plasma membrane against their concentration gradient
Explanation:
Active transport refers to the <u>movement of the particles or molecules from higher concentration to lower concentration, across the plasma membrane of a cell.</u> This transport requires cellular energy as the movement of the molecules is <u>against the concentration gradient</u>.
Active transport can be divided into primary and secondary active transport.
Answer:
Since mg of magnesium oxide is an ionic compound. The metal will transfer valence electrons to the nonmetal.

Fructose-1, 6-bisphosphatase is activated in response to a glucagon signal.
<h3>What is the purpose of Glucagon signals?</h3>
- Glucagon signals specify that fuel molecules are required in the bloodstream.
- So these signals activate Fructose-1, 6-bisphosphatase (F1, 6BP) so as to increase the level of sugar and other fuels required for production of energy.
- In the process of gluconeogenesis, new glucose molecules are synthesized from other non carbohydrate sources.
- As glucose is required in the bloodstream so F-1, 6BP should be activated as it acts as a rate limiting enzyme in gluconeogenesis.
- Gluconeogenesis occurs when the dietary intake of glucose is very low.
- Glucose is required as a source of energy by almost all body cells so in case of less oxygen it is synthesized from other molecules like amino acids.
