Why can't acetyl CoA make glucose? How does protein catabolize into acetyl CoA? What enzyme is responsible for the conversion of pyruvate into lactic acid? What process begins with the production of acetyl CoA? Why are ketone bodies not preferable to glucose? What are the differences between ...
Why is pyruvate converted into acetyl CoA prior to entering the Krebs Cycle? What does this conversion do to the pyruvate molecules? The Krebs Cycle: The Krebs Cycle (also known as the citric acid cycle) refers to the serious of process...
In mitochondria, pyruvate is oxidized to acetyl-CoA, and controlled "combustion" generates energy equivalent to two ATP molecules. The overall sum of the citric acid cycle can be represented as:Acetyl-CoA + 3 NAD+ + FAD + GDP + Pi + 2 H2O → CoA-SH + 3 NADH + 3 H+ + FADH2 + ...
In the subsequent stage of fatty acid biosynthesis, the palmitic acid is converted into palmityl-CoA. This is done using an enzyme system in the cell’s cytoplasm. Unsaturated fatty acids are synthesized by Fatty Acid CoA desaturaseenzymes, which produce double bonds. Each double bond is created...
Since we’re talking about aerobic respiration in this video, let’s assume that oxygen is present and that both pyruvate molecules were converted into two molecules of acetyl CoA, effectively committing to the Krebs cycle. The Krebs cycle is simply a series of oxidation-reduction reactions that...
Since HIF-1 regulates the expression of GLUT-1, a transporter essential for glucose uptake11, and pyruvate dehydrogenase (PDH), an enzyme that converts pyruvate to acetyl-CoA77, HIF-1 may promote UCP1-mediated glucose uptake and oxidative phosphorylation (Fig. 1). However, given that HIF-1...
[100]. For example, PKM2, a key enzyme in glycolysis associated with cell-dependent aerobic glycolysis, catalyzes the final step of glycolysis, which converts phosphoenolpyruvate to pyruvate [101]. A PKM2 agonist (TEPP-46) has been found to inhibit renal fibrosis by suppressing aberrant ...
What is acetyl CoA? Which structural protein of skeletal muscle also act as an enzyme? What does glutamine do to your body and how does it differ from an amino acid? What is the unit of enzyme? Which enzymes become inactive by phosphorylation?
a. Acetyl-CoA b. Oxygen c. The proton gradient established by the Electron Transport Chain. d. Pyruvate The electron transport chain uses the transfer of __ between protein complexes to set up a proton gradient. a. electrons b. ADP c. neutrons d. protons e. ATP W...
What enzyme is responsible for the conversion of pyruvate into lactic acid? What system removes metabolic wastes from the body? Name the functional cell of the liver. What is the role of the kidney in protein catabolism? What nerves and hormones are involved to decrease GFR and why does this...
