The pituitary gland is the gland that triggers other glands to release hormones. It is a pea sized gland attached to the base of the brain. It is important in controlling growth and development and the functioning of the other endocrine glands. Without the pituitary gland, the body wouldn't reproduce, wouldn't grow properly and wouldn't function.
Answer:
Enzymes are the bio-catalyst produced by the body.
They increases the rate of bio-chemicals reaction taking inside the body.
They form enzyme-substrate complex in order to increase the rate of the reaction.
They are highly specific in nature.
Example:
- Hexokinase catalyses the conversion of glucose to glucose-6-phosphate.
- Salivary amylase catalyses the breakdown of starch into maltose (simpler sachharides).
- Protein kinase is an enzyme used to activate or deactivate other by adding phosphate group to them.
Answer:
A plant cell.
Explanation:
Plant cells are part of multicellular organisms. They form tissues and are differentiated. If we see a section of plant cells, we can see that they have a box-like shape. <u>This happens because plant cells, besides the membrane, are surrounded by a </u><u>cell wall</u><u>, which is rigid and gives the cell this form</u>.
They also do photosynthesis, which is a metabolic process where they obtain energy from the radiation of the sun. To capture the photons they have pigments, especially a green pigment called chlorophyll. <u>The chlorophyll is not free in the cytoplasm, it is contained in a bean-shaped organelle called chloroplast, and therefore they give the </u><u>chloroplast this distinctive green color. </u>
