Slightly lesser because kinases phosphorylate a protein by adding a phosphate group. Lower glucose 1-phosphate, thus less glucose 6-phosphate, thus decreased glycolysis reactions. it decreases the respiration rate of Lactobacillus. e. Cellular respiration! j. Is it worth it to review or will the exam just be a random BS-ing of bio information I’ve been reviewing for a couple weeks now, but I feel like everytime I do a practice frq the actual biology I learn isn’t even helpful and I usually just end up bullshitting most of my answers. .   Terms. ... an AP Biology student discovers a previously unknown microscopic organism. .

WIth acetyl-CoA, that is oxidized in Krebs to get even more CO2. Please read through the entire packet and contact Mr. Eberhard with any questions. (edit 1: i'm not too sure to what extent you can show questions so i'm going to delete some of them that are unnecessary to be safe), Oh wow I had the same question but different parts. But for 2a, I thought that since the PK enzyme merely regulates the activity of glycogen phosphorylase, it doesn’t necessarily mean that it decreases the glycolysis reactions, but it could mean that it could create too little or too much (deregulated, so random).
