Insulin is secreted by pancreas.

Further Explanation:

<u>Pancreas</u> acts as the endocrine gland as it secretes <u>hormones like insulin</u>. Insulin decreases the blood sugar level.

The glucose is present inside the vesicle present within β- cell of pancreas. When the glucose level enhances in the blood, glucose is transported inside the β- cell by GLUT 2 and a signaling cascade occurs which results in movement of vesicles to the cell membrane and releases the insulin.

<u>Effects of insulin  are:</u>

1. It facilitates the entrance of glucose into adipose tissue and muscle.

2. It induces the liver to store glucose into the glycogen form.

3. It decreases the concentration of glucose into blood.

4. Promotes the synthesis of fatty acid in liver.

<u>Receptors</u> are the molecules that binds to the ligand and starts cascades of signalling reactions. It is present either in the plasma membrane of the cell or in the cytoplasm or nucleus of the cell.

<span>The major effects of insulin on muscle and adipose tissue are: (1) Carbohydrate metabolism: (a) it increases the rate of glucose transport across the cell membrane, (b) it increases the rate of glycolysis by increasing hexokinase and 6-phosphofructokinase activity, (c) it stimulates the rate of glycogen synthesis and decreases the rate of glycogen breakdown. (2) Lipid metabolism: (a) it decreases the rate of lipolysis in adipose tissue and hence lowers the plasma fatty acid level, (b) it stimulates fatty acid and triacylglycerol synthesis in tissues, (c) it increases the uptake of triglycerides from the blood into adipose tissue and muscle, (d) it decreases the rate of fatty acid oxidation in muscle and liver. (3) Protein metabolism: (a) it increases the rate of transport of some amino acids into tissues, (b) it increases the rate of protein synthesis in muscle, adipose tissue, liver, and other tissues, (c) it decreases the rate of protein degradation in muscle (and perhaps other tissues). These insulin effects serve to encourage the synthesis of carbohydrate, fat and protein, therefore, insulin can be considered to be an anabolic hormone.

A cladogram is a type of graph that shows how closely related different types of organisms are in an evolutionary context. It resembles a tree, with various organisms being placed at the end of each branch. If two organisms have a close common branch, they are more closely related than those who have more distant branches. Since DNA, or corresponding protein sequences are more similar in closely related species, and more different in more distant species, a biologist can use those sequences to numerically determine how closely related three species are.
