Glucagon is a hormone that is released when the level of glucose in the blood is low. Glucagon uses a G protein signaling pathway to promote glycogenolysis. Write down the steps of the signal transduction pathway in order from the releasing of glucagon into the blood to the promotion of glycogenolysis.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
