The Prostate gland

The prostate is a walnut-sized organ that surrounds the first part of the urethra. It is located between the bladder and the penis. Semen is formed by the prostate by combining a thick white fluid it initially produced with the sperm from the testicles. It also produces an antibiotic protein known as prostate-specific antigen (PSA) that changes the semen into liquid.

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.
