edit The Spread (or Bid-Ask spread). The âbid-ask spreadâ is the difference between the bid and ask prices for a security. The percent spread can be calculated as follows: The spread is retained as profit by the broker who handles the transaction and pays for related fees.
The overall reaction of glycolysis which occurs in the cytoplasm is. represented simply as: C 6 H 12 O 6 + 2 NAD + 3 (C=O)COOH + 2 ATP + 2 NADH + 2 H +. At this time, concentrate on the fact that glucose with six carbons is converted into two pyruvic acid molecules with three carbons each.
â¢ The hydrogen (and energy) required for this reaction is supplied by NADH and H + , producing NAD + . â¢ The NAD + produced funnels back into glycolysis to oxidize more glyceraldehyde-3-phosphate (step 6), providing a small amount of ATP. This reaction occurs in the cytosol. 2014 Pearson Education, Inc. Regulation of Glycolysis â¢ The main step of regulation in glycolysis is step 3. â¢ The enzyme phosphofructokinase, which catalyzes the phosphorylation of fructose-6-phosphate to fructose-1,6-bisphosphate, is heavily regulated by the cells.
