What tropic hormone stimulates cortisol from the adrenal gland?
zhuklara [117]

Answer:

c) adrenocorticotropic hormone (ACTH).

Explanation:

A tropic hormone is defined as the hormone which is secreted from one gland and acts on another gland. ACTH is released by anterior portion of our pituitary gland during the condition of biological stress. After it is released, it acts on adrenal gland so that adrenal gland could secrete another hormone named as cortisol (steroid hormone). In response to stress, cortisol increases blood sugar level, elevates brain's use of glucose etc. so as to counter stressful situation.

Apart from this cortisol also helps in regulating our metabolism, reduces inflammation and controls salt and water balance.

When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis ____________ .
Andrei [34K]

Answer:

When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis  decreases.

The process of conversation of stored glycogen in the liver and muscles  to glucose is Glycogenesis. It takes place when the blood glucose drops,below certain levels and the body cells need glucose for biochemical activities.Therefore, when there are excess CHO consumption,more glucose would be in the blood,and thus no need for glycogenesis.(breakdown of glycogen)

Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy __Increases__________ and oxidation of fat for energy ___decreases_________ .

Definitely, this is a simple logic.As the storage for glycogen is limited,excess glucose  move into the blood, since they can not be converted to glycogen.The glucose is expended through cellular reduce the amount in the blood. Therefore, Gluconeogenesis, the production of glucose from non-CHO substances drops. Hence beta- oxidation drops.

Overall, when carbohydrate intake is excessive, lipogenesis increases.The process of converting excess CHO to fatty acids.Biochemically it is the process of converting the Carbon precursor of acetyl co -A to fatty acids.Therefore this increases to synthesized more fatty acids from CHO
