<span>If there is not enough carbohydrate available in cells to allow the acetyl-CoA to enter the citric acid cycle, it will be used to make ketones. Acetyl-CoA is a molecule that is important in some biochemical reactions involving protein lipid and carbohydrate metabolism. It function to transport an acetyl group to the citric acid cycle or the Krebs cycle for it to be oxidized for the production of energy. Ketone can be produced and is regulated from the acetyl-CoA. The rate of the production of this substance would increase during starvation or in other words there is less carbohydrates that is available in the body.</span>
Answer:
D
Explanation:
The atmosphere is not an eycosystem
Before assessing the two given cases, an assumption needs to be made about the digestion of the two types of food items, corn and beef. Let us assume that both get digested by expending same amount of energy by the human body. Let the amount of energy at producer level be an arbitrary X.
Case 1: Corn to human:
Since corn is at the producer level, it will have X amount of energy. The transfer of energy from corn to human will take place with a loss of 90% energy at the producer level. Hence the humans will receive 10% of X amount of energy.
Case 2: Corn to cow to human:
Since corn has X amount of energy, only 10% will pass to the next level, i.e. cow. So cow has 10% of X. Cow transfers only 10% of the energy that it has. Hence humans receive only 10% of 10% of X amount of energy.
It can be seen that humans receive more energy in case 1 than case 2. Hence we can say that it is more efficient for humans to feed on corn.
Temperature is related to heat by science
Answer:
