1. Answer;
A.transport energy
Explanation;
-ATP is a biological molecule, which is a product of the cellular respiration, it performs many essential roles in the cell. It is the major energy currency of the cell, providing the energy for most of the energy-consuming activities of the cell.
-An ATP molecule releases approximately 30kJ (mol^-1) of energy
.
-Energy from an ATP molecule is released in small quantities to prevent damage to the cell
.
-Energy released is used for metabolism in the cell. Other reactions that require energy from ATP include; active transport/ muscle contraction/ glycolysis.
2. Answer;
D. Autotrophs produce organic molecules
Explanation;
-Most autotrophs use a process called photosynthesis to make their food.
-In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy.
-Light energy is absorbed by chlorophyll, a green pigment found in chloroplasts in some plant cells and algae. Absorbed light energy is used to convert carbon dioxide (from the air) and water (from the soil) into a sugar called glucose. Oxygen is released as a by-product.
