The reactions release chemical energy that the cells can use to power growth and other important cell processes
Answer:
Mitochondrial proteins enter the organelle through channels formed by membrane proteins present in its inner and outer membranes.
Explanation:
All the biological membranes have lipid bilayer with the non-polar core that does not allow entry of charged and large substances. Mitochondrial proteins are synthesized in the cytosol and the unfolded proteins bind to the chaperons that deliver them to the receptors present in the outer mitochondrial membrane.
The receptor moves the protein to the membrane channels formed by integral membrane proteins of inner and outer mitochondrial membranes. The proteins enter the intermembrane space and are targeted to the inner membrane through channels while chaperons are left outside only.
Answer:
The contractile ring shrinks through the center of the cell, evenly dividing the cytoplasm between the two halves. This indicates that cytokinesis is completed and the cell has been replicated.
Answer:
Kidneys
Explanation:
ADH is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced.
Answer:
DNA, found within the nucleus, must be replicated in order to ensure that each new cell receives the correct number of chromosomes.
