The Krebs cycle occurs in the mitochondrial matrix of a cell.
Hope this helps!

MitochondriaMitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called aerobic respiration and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.</span>
Carbon moves from living things such as plants to the atmosphere through the process of respiration. During respiration plants utilize oxygen and glucose to obtain energy resulting in the release of carbon dioxide, water and ATP. The carbon dioxide is then released to the atmosphere. The second way in which carbon dioxide is released to the atmosphere from plants is when the plants die, they are decomposed and carbon atoms are returned to the atmosphere.
Answer:
The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides.
Explanation:
This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.
