The ball will have the same amount of potential energy no matter where it is placed. 10. Which one of the following is the most common energy "currency" for a cell? A. ATP B. DNA C. glucose D. protein E. NADH

Explanation / Answer

1. Answer is A

Explanation : Metabolism is a sum total of anabolism and Catabolism, Anabolism is a synthetic process in which micromolecules and energy are added to form Macromolecule, so it is a energy saving process. while Catabolism is a destructive process in which macromolecules are broken to release energy and micromolecules.

2. Answer is B

Explanation is given above

3. Answer is D

Explanation : Autoroph : prepare there own food, from Inorganic Substance

Heterotroph : Recieve Food in form of Organic Substance

PHOTOAUTOTROPH : prepare their their own food from inorganic molecules in presence of Light energy

CHEMOAUTOTROPH : prepare their own foor from Inorganic molecules in presenece of chemical energy

CHEMOHETEROTROPH : prepare or Recieve their own food from Organic Molecules and Chemical Energy

4. ANswer is A Phototroph are those organnism those prepare their food in presence of Light Energy from Organic or organic molecules.

5. Answer is E
