Re: Cellular respiration questions..

... At the beginning of glycolysis it used 2 ATP to activate glucose, which results in the C6 molecule splitting and C3 pyruvate resulting (G3P). The energy investment step requires 2 ATP, and the energy harvesting step produces 4 ATP. Totaling in a net gain of only 2 ATP. During the krebs ...

Biology help plz !!

... you stop? (a little stupid question, but that's problem of naming, not question;) So, you have to add this reaction's product in order to form G3P (or any intermediate in between). AND So, if will you run these reactions, what cofactors will you need? And which substances will be formed? How ...

enzymes in cold temperature

... turnover number (Kcat) is about 600,000 molecules of product per second. The other perfect enzyme Triose Phosphate Isomerase ( converts DHAP to G3P to avoid a harmful intermediate) that is crucial in glycolsis is also only slowed down by the rate of diffusion (Kcat of about 3000 molecules of ...

Glycolysis, Step 6

in Harper's biochemistry ,you find that G3P isn't directly coverted to1,3 biphosphoglycerate . through this indirect conversion hydrogen removed and carried on NAD+ and doesn't come from Pi
