Yes. In the beginning, glycolysis requires 2 ATP molecules.
One ATP allows for the phosphorylation of the glucose molecule to fructose-6-phosphate and another phosphorylation to fructose-1,
6-biphosphate. The fructose-1, 6- bisphosphate
is then cleaved into two glyceraldehyde-3-phosphates that then enter the energy
generating part of the glycolysis biochemical reaction.
Enzymes. There are 3 main types: Peptidase, Lipase, and amylase :) hope that helps! I'm learning that stuff too :)
Substance abuse can spread STIs because when a user shares needles with an infected person, it can spread through the blood. Any high-risk behavior like this spreads STIs.
