Your friend should stay away from foods which are high in simple sugars, which do not need to be metabolized by enzymes (hydrolysis reactions) to be consumed by cells. Complex sugars which are linked together in polysaccharides are broken down over time, keeping blood sugar levels from dramatica...
What is the purpose of glycolysis? Write a balanced equation which describes the overall pathway. Which of the following enzymes in glycolysis catalyzes a step that involves the production ATP? a) Glyceraldehyde-3-phosphate dehydrogenase b) Phosphofructokinase c) Pyruvate kinase d) Hexokinase ...
7, how do you predict the direction of the reaction? How cell control △G? G = G'o + RT ln Q Cell controls △G by controlling Q (concentration).. Preview2 1. Briefly describe the 10 steps of glycolysis only indicating the reactants and products. Where does it happen? How ...
Hexokinases areintracellular enzymesthat phosphorylate glucose, mannose and fructose to the corresponding hexose 6-phosphates. The resulting phosphate esters can then be broken down to pyruvate by glycolysis or used for different biosynthesis. Hexokinases play an important role in the control of glycolysi...
Why is this type of intracellular digestion intensified in an organism experiencing starvation? A) What enzymatic reaction does glucokinase perform in metabolism? How does it differ from other hexokinases, and why is this important in pancreatic Beta cells? B) Explain and describe the pathways that...
HIF-1 can be activated selectively under hypoxic conditions (yellow color; left side of the diagram), regulating many enzymes involved in the glycolysis pathway, including GLUT1, HK, and PDK. PDK in turn blocks pyruvate conversion to acetyl-CoA in the mitochondria, thereby decreasing oxidative ph...
However, gating (see above) or compartmentalization of pyruvate metabolism (as suggested in Fig. 5) would prevent the uncoupling cycle from occurring. While association of hexokinase (the first enzyme of the glycolytic pathway) with mitochondria has been known for many years [37], it was shown ...
Your friend should stay away from foods which are high in simple sugars, which do not need to be metabolized by enzymes (hydrolysis reactions) to be consumed by cells. Complex sugars which are linked together in polysaccharides are broken down over time, keeping blood sugar levels from dramatica...
