The answer to this question is: carbohydrate.
There are 3 kinds of macromolecule class: carbohydrates, lipid and protein. Carbohydrate used mostly for energy. The example for this class sugar, fiber and starch.
Lipid can be used for energy storage and make some hormone. The protein used for making muscle and cells component.
DNA is composed of nucleotides
Answer:
ATP can add phosphate groups, thereby releasing energy that can be used in cellular processes
Explanation:
Adenosine triphosphate (ATP) is the energy currency of the cell. It is produced during cellular respiration. It stores energy in the terminal phosphtae bond.
When the terminal phosphate group is removed in the presence of ATPase enzyme, ATP is converted to adenosine diphosphate (ADP), inorganic phosphate (pi) and energy.
Thus, on removal of phosphate group from ATP, ADP is formed and releases energy. The energy can be used in cellular processes
Answer:
D. Active transport.
Explanation:
Active transport is the method that uses the ATP's energy to move ions and molecules from one side to the other of the membrane. The elements move from a place of lower concentration to one of a higher concentration. They move against their concentration gradient, which is why they need the energy to do it. There are two types of active transport, primary and secondary.
The primary active transport is ion pumps that hydrolyze ATP using one of the phosphates of the ATP to change the pump's shape and move the elements against their concentration gradient. It uses the ATP's energy directly.
The secondary active transport does not use ATP directly. It uses the electrochemical gradient that the primary transport had created when hydrolyzing ATP to transport the ions and molecules.
