Answer:
Just looking at these answers none of them seem particularly right as sunlight is used as the energy source to make glucose meaning that it is used as energy to bond hydrogen, carbon, and oxygen. The most right answer however i think is that it is converted into chemical energy.
Answer: The main function of Cellular respiration is to convert glucose into energy source (ATP).
Explanation: Cellular respiration is process in which chemical energy of food is released and turn into ATP. This process incudes three steps: Glycolysis, Kreb Cycle and electron transport chain.
Glucose can not be directly used as energy. By the process of Cellular respiration 1 glucose molecule gives 38 ATP molecules.
to make ATP, H+ ions will flow through the ATP synthase. this movement through ATP synthase will create enough energy for ATP to be formed.
There are many factors to look for to determine a living organism. such as Nutrition, Reproduction, Sensitivity, Growth, Movement, Respiration, and Excretion.
TBut the most important that you can apply to all living organisms, even viruses are: Reproduction (it use the host to increase their number) and nutrition (it take energy from the host to replicate itself).
