Answer:C
Explanation: The reason why i picked C is because oxygen is the gas that is taken in the human body for cells to make energy in the mitochondria. Carbon dioxide and energy are the ones that are taken out, and are not in need.
Energy releasing reactions need to take place so we can function. Without energy we can not move around. A great source of energy is food and plenty of water.
Answer:
No
Explanation:
Technically, this is inaccurate. To say that glycolysis produces two ATP molecules strays from the input of ATP needed. Overall, 4 ATP molecules are produced during glycolysis. However, there is an input of 2 ATP molecules at the beginning. Therefore, the correct statement would be that glycolysis produces 2 net ATP molecules, not that glycolysis produces 2 ATP molecules. (The word net makes a big difference!!).
Answer: photosynthetic bacteria
Explanation:
