Question

The inner membrane of mitochondria is very selective with respect to entering molecules. Name a molecule that regularly enters in it
A. Pyruvic acid
B. Glucose
C. ATP
D. Oxaloacetic acid

Answer 1

Proteins account for approximately 80 percent of the inner mitochondrial membrane content, which has a significant effect on the processes that generate mitochondrial developmental and evolutionary specializations.

Complete answer:
Mitochondria are organelles that are unusual. They act as the power plants of the cell, are surrounded by two membranes, and use their own genome. They also differentiate independently of the cell in which they reside, indicating that mitochondrial replication is not associated with cell division. All of these attributes are the cornerstones of ancient mitochondrial ancestors, who were probably prokaryotes who lived openly.

The inner membrane of the mitochondria is the source of the chain of transport of electrons (aerobic respiration) containing the respiratory chain enzymes. Succinate dehydrogenase is a member of the respiratory complex II found in the inner mitochondrial membrane and responsible for the conversion of succinate to fumarate in the development of citric acid. Embedded in the inner mitochondrial membrane, the enzyme ATP synthase assists in the synthesis of the ATP molecule (cell energy currency). First of all, cellular respiration takes place in the cytoplasm and then in the mitochondria.

In the cytoplasm, glycolysis occurs in which glucose splits into two pyruvates that are transferred via an inner mitochondrial membrane that conducts the cycle of Krebs to the mitochondria. To begin the Krebs cycle and complete cellular respiration, this pyruvate periodically reaches the mitochondria.

So, A-'Pyruvic acid' is the right alternative.

Note: The inner mitochondrial membrane is the home for the oxidative phosphorylation proteins, and within the membrane, the proteins are packed very tightly. It has also recently been used in inflammatory acne, mild acne scars, greasy skin, actinic keratosis, and warts as a medium chemical peeling agent.
