Answer;
B. build ATP molecules from ADP.
Explanation;
-Cells do not use the energy from oxidation reactions as soon as it is released. Instead, they convert it into small, energy-rich molecules such as ATP and nicotinamide adenine dinucleotide (NADH), which can be used throughout the cell to power metabolism and construct new cellular components.
-Cells need energy to accomplish the tasks of life. Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Answer:
The correct answer is B. build ATP molecules from ADP
Explanation:
Food taken in by the body is in complex form which is broken down in simpler form like glucose by the enzymes present in our body. Then this simpler form is absorbed in the blood through intestine.
Then this glucose is taken in by body cells which oxidize this glucose into carbon dioxide and water during respiration process. This oxidation of glucose release energy which is stored in the form of ATP in the body.
ATP is produced by the addition of a phosphate group into the ADP molecule by ATP synthase enzyme present in mitochondria. Therefore the right answer is B.
