Each ATP molecule is composed of three separate subunits. Which of the following is NOT a proper description of one of these subunits? A) three carbon-nitrogen rings B) an adenine C) a five-carbon sugar D) a triphosphate group E) a ribose 54. Which of the following sequences accurately represents the flow of electrons during photosynthesis? A) NADPH-02- CO2 B) NADPH-chlorophyll Calvin cycle C) NADPH- electron transport chain 02 D) H20-NADPHCalvin cycle E) H0-ATP- >Calvin cycleExplanation / Answer
50-Life gains most of it's energy from sunlight.
Plants , some bacteria use sunlight for the process of photosynthesis in which they produce carbohydrate, which is major source of ATP production.
51: A) transferred and transformed but not created or destroyed.
52- one phosphate is removed.
ATP stands for Adenosine triphosphate containing 3 phosphate molecules and ADP stands for Adenosine Di phosphate containing two phosphate molecules. ATP is hydrolyed to ADP by removing one phosphate and energy released during this process is used for various metabolic reactions in body
53- A: 3 carbon nitrogen rings.
The ATP structure of consists of Ribose sugar which has 5 carbon atoms in it; a Triphosphate group and adenine which has 2 carbon- nitrogen rings.
