Answer:
nucleotides
The DNA molecule is a polymer of nucleotides. Each nucleotide is composed of a nitrogenous base, a five-carbon sugar (deoxyribose), and a phosphate group.
Explanation:
"It converts the inactive enzyme pepsinogen into the active enzyme pepsin, which is responsible for digesting proteins in your stomach. HCL also helps digest other foods in your stomach. Ultimately, HCL is neutralized by chemicals secreted in your small intestine."
But, use your own words, though. Because I just hit copy & paste. Hope this helps!
Well, when chromosomes cross over during prophase 1 of meiosis, the homologous pair of chromosomes exchange segments of DNA which happen to be the genes. So the significance of crossing-over during prophase 1 is that it adds genetic variation to sexually reproducing organisms.
<u>Answ</u>er:
False
,Cellular respiration not is the oxygen dependent process through which food molecules are broken down and the energy released used to generate atp.
<u>Explanation</u>:
Glycolysis is the primary phase in the collapse of glucose to abstract energy for cellular metabolism. Almost every living organisms bring out glycolysis as step of their metabolism. The method does not use oxygen and is hence anaerobic. Glycolysis occurs in the cytoplasm of equally prokaryotic and eukaryotic cells. Glucose arrives into the heterotrophic cells in two ways.
1. Over secondary active movement in which the movement occurs against the glucose concentration gradient.
2. Over a cluster of vital proteins called GLUT proteins, also called as glucose movement proteins. These transporters helps in the simplified diffusion of glucose.
