Endoplasmic reticulum serves as transpiration area. The correct option is B.

<h3>What is endoplasmic reticulum?</h3>

The endoplasmic reticulum (ER) is a large, dynamic structure in the cell that performs numerous functions such as calcium storage, protein synthesis, and lipid metabolism.

The ER's various functions are carried out by distinct domains, which include tubules, sheets, and the nuclear envelope.

The endoplasmic reticulum can be smooth or rough, and its function is generally to produce proteins that allow the rest of the cell to function.

Ribosomes, which are small, round organelles that make proteins, are found in the rough endoplasmic reticulum.

Thus, the correct option is B.

Adrenaline stimulates glycogen breakdown in skeletal muscle cells by ultimately activating glycogen phosphorylase, the enzyme th

r-ruslan [8.4K]

Answer:

d) A constitutively active mutant form of PKA in skeletal muscle cells would lead to an excess in the amount of glycogen available.

Explanation:

This occurs in the process of Glycogenolysis. The process involves breaking down of glycogen to glucose -1- phosphate and glycogen which helps in the release of glucose into the blood stream to prevent hypoglycemia(low blood sugar). The glucose-1-phosphate is later converted to glucose -6-phosphate. The latter enters the glycolytic pathway in which the reaction is catalysed by the enzyme phosphoglucomutase.

This homeostatic glucose regulation is regulated by the protein kinase(PKA)/ cAMP pathway in the skeletal muscles, the liver and the pancreas.

How are Mitosis, meiosis, Genetics, DNA and Mutations connected to one another?

jonny [76]

Mutations can occur before, during, and after mitosis and meiosis. If a mutation occurs in cells that will make gametes by meiosis or during meiosis itself, it can be passed on to offspring and contribute to genetic variability of the population
