Answer:
D. catabolic reactions
Explanation:
Metabolism employs catabolic reactions to break down large molecules (nutrients) carbohydrates, fats, proteins as food is ingested. Then they degrade the molecules , being smaller and releasing the energy we need in order to function. The metabolic processes ocurr in all cell of the body.
Catabolism and anabolic reactions are good companions as they occur together.
Answer:
d. with just a few nights of sleep deprivation, but recovery will take more than a month of normal sleep
Explanation:
During sleep, the body heals itself, wear and tear of cells occur, and the chemical balance of hormones and neurotransmitters is restored. During sleep, the body prepares cytokines, that are protection and infection-fighting substances. Sleep deprivation prevents the production of cytokines and the ability to fight and prevent infections decreases. Sleep also enhances the T-cell responses which are associated with lymphocyte production pathway. Hence, people who remain awake have a lesser T-cell count due to decrease activation of T-cells. Hence, a few nights of sleep deprivation makes the immune system lack behind in the T-cell response generation. This low T-cell activity does not only impede the production of immune system cells but also reduces the functioning of existing cells such as decrease in cytokine functioning. Hence, the entire immune system cells needs a double amount of sleep functioning to keep track of immune system responses and rebuild the cells.
Answer:
The correct answer will be option B.
Explanation:
Blood pressure represents the pressure of the blood in the major arteries of the body.
This blood pressure increases in the arteries when the ventricle contracts to push the blood to the major artery by a mechanism called ventricular systole. This increased blood pressure number is known as systolic blood pressure which is usually 180 mm of Hg.
The blood pressure decrease in the artery due to ventricular diastole during which ventricles relaxes. This lower number of blood pressure is known as diastolic blood pressure which is 80 mm of Hg.
Thus, option B is the correct answer.
