Answer:
Glucagon signals the liver to start producing glucose.
Explanation:
Glucagon signals the liver to start producing glucose from the breakdown of amino acids through gluconeogenesis process. When the glucose level decreases in the body due to fasting or starvation, the pancreas release glucagon which provides signals to the liver to produce glucose form non carbohydrates substances present in our body. This production of glucose increases the concentration of glucose in the blood and the body used this glucose for the generation of energy molecules in the form of ATP.
Answer:
When the required direction of transport is opposed to concentration levels, a cell <u>will </u> expend energy to force<u> ions</u> across its membrane.
Explanation:
If the concentration gradient is opposite to the direction of transport of minerals, then the cell will use energy to transport mineral ions from a lower concentration to a higher concentration. The most common process through which this happens is termed as the active transport.
The process of active transport is opposite to passive transport. In passive transport, molecules move from a higher concentration to a lower concentration.
