Which of the following best explains how insulin injections affect signal transduction in an individual with type 1 diabetes
Reptile [31]

Answer:

The correct answer is - option A. They serve as second messengers to regulate glucose uptake to cells.

Explanation:

Type one diabetes is a condition that is characterized as the inability to produce enough quantity or at all of the insulin by the beta cells of the pancreas. Therefore, a patient with this condition completely depends on exogenous insulin to maintain the sugar level in the blood.

Insulin is the hormone that removes the excess amount of glucose from the blood by the adipose tissue, liver cells, and skeletal muscle that uptake an extra amount of sugar. there are receptors present on the surface of the plasma membrane which binds with the insulin and acts as a secondary to regulate a cascade reaction to glucose uptake to cells.

Can humans live underwater what are some things to consider
timurjin [86]

Underwater living faces many of the same life support challenges as living in space. ... But in the future, underwater habitats might provide their own oxygen with artificial gill technology to extract dissolved air from the sea water

Since humans do not have gills, we cannot extract oxygen from water. Some marine mammals, like whales and dolphins, do live in water, but they don't breathe it. They have developed a mechanism to hold their breath for long periods of time underwater.

To put these depths into perspective, three American football fields laid end to end would measure 900 feet (274.32 m) long — less than the distance these divers reached underwater. Most recreational scuba divers only dive as deep as 130 feet (40 meters), according to the Professional Association of Diving Instructors.

List and describe the functions of carbohydrates in the body. Explain how the body maintains glucose levels, including which hor
kicyunya [14]

Answer:

There are different function performed by carbohydrates in the body like-

Storage: When there is excess glucose present in the body they are stored as glycogen in muscles and liver.

Providing energy: Carbohydrates are the primary source of energy for the cells present in our body.

Carbohydrate helps to spare proteins and lipids and helps in providing polysaccharides for membrane carbohydrates.

The body maintains blood glucose levels through hormones. For example, when the blood glucose level gets high insulin is released in the blood by the pancreas which reduces the blood glucose level by accumulating glucose as glycogen in the liver and muscle.

Glucagon works opposite to insulin and increases the blood glucose level.
