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.
Protein channels + no energy spent + following concentration gradient = passive transport via facilitated diffusion :)
The answer is A. <span>Energy taken from ATP and NADPH is used to make energy-rich carbohydrates.
The light-independent reactions are reactions in which ATP and NADPH is used for the conversion of carbon dioxide into </span><span>energy-rich carbohydrates. So, the carbohydrates are produced and not used up as stated in choice B. Carbon dioxide is neither broken off of molecules with three carbons nor were used up in the light-dependent reactions, leaving choices C. and D. as wrong ones.</span>
It is Nucleic Acids, they consist of long chains of units like the proteins, but still both are different.
