<span>Humans have pores in their skin to sweat and cool off the body. Plants have similar structures called stomata. Through these structures, plants can do the same things humans can through their pores, such as release the heat from them, as well as unnecessary chemicals through "sweating." Tendrils are stems, pores are called stomata, and not pores when it comes to plants, and receptacles are parts of the stem where flower organs grow.</span>
<span>A large complement of decomposers rapidly turns dead plant and animal matter into nutrients that are quickly taken up by plants.
Also, some animals live on eating plants, other animals eat those that live on plants, and animals that live on eating other animals die to make nutrients that are eaten by plants; this also, is called an ecological food chain.</span>
Answer:
A. His mitochondria lack the transport protein that moves pyruvate across the outer mitochondrial membrane.
Explanation:
Pyruvate is from the breakdown of carbohydrates such as glucose through glycolysis. Glucose enters the cytosol through specific transporters (the GLUT family) and is processed by one of several pathways depending on cellular requirements. Glycolysis occurs in the cytosol and produces a limited amount of ATP, but the end product is two 3-carbon molecules of pyruvate, which maybe diverted again into many pathways depending on the requirements of the cell. In aerobic conditions, pyruvate is primarily transported into the mitochondrial matrix and converted to acetyl-coenzyme A (acetyl-CoA) and carbon dioxide by the pyruvate dehydrogenase complex (PDC).
Initially it was proposed that pyruvate was able to cross the membrane in its undissociated (acid) form but evaluation of its biochemical properties show that it is largely in its ionic form within the cell and should therefore require a transporter.
Transport of pyruvate across the outer mitochondrial membrane appears to be easily accomplished via large non-selective channels such as voltage-dependent anion channels/porin, which enable passive diffusion. Indeed, deficiencies in these channels have been suggested to block pyruvate metabolism
A possible consequence of deforestation in the carbon cycle is increased atmospheric carbon (Option D).
<h3>What is the carbon cycle?</h3>
The carbon cycle refers to the movement of this element (carbon) between biotic and abiotic factors.
Carbon is a harmful greenhouse gas present in the atmosphere which is associated with climate change.
In conclusion, a possible consequence of deforestation in the carbon cycle is increased atmospheric carbon (Option D).
