Introduction:
Human body requires glucose, fats, and proteins as the fuel that comes from the diet we intake. There are a number of different hormones involved in the food
Answer to Problem 27A
Correct answer:
The correct answer is option (C) Glucagon.
Explanation of Solution
Explanation/justification for the correct answer:
Option (C) Glucagon. Glucagon is a peptide hormone that is secreted from the alpha cells of the pancreas. Glucagon raises blood pressure by stimulating the liver to perform glycolysis and digesting glucagon causing the release of glucose in the blood circulation. So, the correct answer is option (C).
The explanation for the incorrect answer:
Option (A) Antidiuretic hormone(ADH). ADH is secreted by the pituitary gland and regulates the amount of water in the blood by the reabsorption from the filtrate in nephrons. It does not affect the blood glucose concentration so, this is an incorrect answer.
Option (B) Growth hormone. The human growth hormone is secreted by the pituitary gland and is responsible for the long bones and muscles. Thus, is not related to the blood sugar level making it an incorrect option.
Option (D) Insulin. Insulin is a peptide hormone that is estimated to play the central role in the anabolism of the body and is produced by beta cells of the pancreatic islets. Insulin manages the metabolism of carbohydrates, fats, and protein by improving the absorption of glucose from the blood into the liver, fat, and skeletal muscle cells. Then it is converted into either glycogen by glycogenesis or fats through lipogenesis. Insulin works exactly opposite the glucagon and decreases the blood glucose level so, this is an incorrect option.

In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardIf a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forward

Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references.
