cestrela7 [59]

Answer:

Scientists studying the effects of warming on boreal forests which change the biome.

Explanation:

The main effect of warming on boreal forests is to change the biome because the plants and animals will not tolerate the increased temperature which occcurs due to climate change so the plants and animals disappeared from the boreal forests and change its biome. The animals migrated to other suitable environment where they continue its growth and increase their population.

Inner mitochondrial membrane hosts several enzymes required for electron transport chain. To increase the amount of energy production per mitochondria, the inner Mitochondrial membrane is folded.

<h3><u>Explanation</u>:</h3>

Mitochondria is one of the membrane bound organelles of the eukaryotic cells. It has a bilayered membrane that has the inner membrane which is selectively permeable and the outer mitochondrial membrane which is mostly permeable.

The inner mitochondrial membrane is highly folded to form the cristae. They hosts the maximum amount of enzymes in form of 4 complexes which are required for the electron transport chain. So to host maximum amount of enzyme in the membrane and to maximise the production of ATP the inner Mitochondrial membrane is folded.

Oligomycin is a type of antibiotic that binds with the F0F1 channel blocking the flow of proton thereby blocking formation of ATP. In presence of Oligomycin, the channel is blocked, leading to the increase in the proton concentration in the innermembrane place. As the maximum concentration is reached, the NADHs aren't accepted by the enzyme for oxidation and proton donation. So they accumulate in the mitochondrial matrix.
