Question 6 2 pts Select ALL the TRUE statements regarding PD

Question 6 2 pts Select ALL the TRUE statements regarding PDH complex. Thiamine deficiency causes Beriberi due to inadequate PDH activity in the brain. Cytosolic PDH has a higher Km than the mitochondrial PDH, since you want most pyruvate in the mitochondria. PDH is found on the mitochondrial membrane. It is encoded by a single gene.

Solution

Answer:

number 6- True answer is- PDH i.e Pyruvate dehydrogenase complex found in mitochondrial matrix

answer 4-

The prosthetic group of cytochrome complex contain heme or \" Iron\" as its metallic component

answer-5

The passage of electron through the varies complexes and Q cycle may produce highly reactive species

i.e O2^- ( superoxide radical) and H₂O₂ (hydrogen peroxide) that may cause harm to the cell if produced in higher concentration

answer 6-

The inner membrane protein \" NADH-Q reductase complex\" directly catalyzes the reduction of O2 to H2O

answer 7-

NADH and FADH2 are strong reducing agents and ready to donate their electons while O2 is a strong oxidising agent and is ready to accept electrons

AS we know, strong reducing agents have high electron transfer potential.
