Homework Answers
If impairment in the enzyme pyruvate dehydrogenase ( which present in eukaryotes cells inside the mitochondrial matrix) them body is not able efficiently break down nutrients into food to be used for the energy,so it is difficult to produce energy from dextrin(which is form of sugar) .

1.Predict the effect of a large amount of acetyl-CoA on the activity of pyruvate dehydrogenase and the rate of glycolysis. Note: pyruvate dehydrogenase is the enzyme that catalyzes the formation of acetyl-CoA from pyruvate. a. Pyruvate dehydrogenase activity will decrease while the rate of glycolysis will increase. b. Both pyruvate dehydrogenase activity and the rate of glycolysis will decrease. c. Pyruvate dehydrogenase activity will increase while the rate of glycolysis will decrease. d. The rate of glycolysis will increase, thereby,...

1. The pyruvate dehydrogenase complex converts pyruvate to acetyl-CoA. What are the steps that pyruvate undergoes? Which coenzymes are involved in each step? 2. Mitochondrial extracts from pigeon breast muscle were incubated with Experiment 1: Amytal, an inhibitor of complex I Experiment 2: Malonate, a competitive inhibitor of succinate dehydrogenase Which experiment will yield more ATP when the cycle is primed with intermediates?

please explain answer
Regulation of Lactate dehydrogenase (same enzyme described above). Lactose dehydrogenase (LDH) is a tetramer that can be regulated in several different ways. The crystal structure of the four subunits of lactate dehydrogenase is shown below. In the heart, lactose has a higher affinity for pyruvate than in the skeletal muscle. Analysis of LDH has identified that it is a substrate of FGFR tyrosine kinase, which results in an increase in the production of lactate. Some types of...
What would be the effect of a mutation that enhances the activity of pyruvate dehydrogenase kinase?...
What would be the effect of a mutation that enhances the activity of pyruvate dehydrogenase kinase? O There will be a buildup of lactate as the cells turn to fermentation for their energy requirements. O There will be an increase in fatty acid production as the concentration of acetyl CoA increases. O There will be an increase in the activity of the citric acid cycle with the increased production of acetyl CoA. The cell will begin to convert acetyl CoA...
