CELL RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What happens in both respiration and photosynthesis?
A
Triose phosphates are decarboxylated.
B
NADPH is produced
C
ATP is produced
D
Electrons pass through ATP synthase.
Explanation: 

Detailed explanation-1: -Both are processes within the cell which make chemical energy available for life. Photosynthesis transforms light energy into chemical energy stored in glucose, and cellular respiration releases the energy from glucose to build ATP, which does the work of life.

Detailed explanation-2: -The cell uses ATP as an energy currency, in the same way that we use money. Actual energy is made through carbohydrates, fats, and other molecules, but they convert this into ATP through respiration.

Detailed explanation-3: -One glucose molecule is metabolised to yield 38 ATP molecules during cellular respiration. The electron transport system produces 34 molecules of ATP out of a total of 38 molecules.

Detailed explanation-4: -Photosynthesis is the process by which energy is converted to chemical energy in plant cells. In cellular respiration plants use the chemical energy stored during photosynthesis in basic life processes. During both photosynthesis and cellular respiration, energy is converted.

Detailed explanation-5: -Hint: Both respiration and photosynthesis synthesise ATP therefore both require the transfer of electrons with the help of those substances that help in the synthesis of ATP.
