CELL RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
photosynthesis reverses the direction of electron flow compared with respiration
A
true
B
false
Explanation: 

Detailed explanation-1: -Cellular respiration and photosynthesis are direct opposite reactions. Energy from the sun enters a plant and is converted into glucose during photosynthesis. Some of the energy is used to make ATP in the mitochondria during cellular respiration, and some is lost to the environment as heat.

Detailed explanation-2: -The principal difference, however, between photosynthesis and respiration is that photosynthesis utilizes carbon dioxide and water in the presence of light to produce glucose and oxygen, whereas respiration uses oxygen and glucose to power the activities of the cell.

Detailed explanation-3: -2. In respiration, the electrons flow from high to low energy, whereas in photosynthesis the electrons flow from low to high energy. 3. In respiration, the final electron acceptor is oxygen whereas in photosynthesis the final electron acceptor is ferredoxin.

Detailed explanation-4: -To be specific, reverse photosynthesis is a process by which solar energy stored in chlorophyll breaks substances in plant down into sub products under the assistance of an enzyme; some can be applied as chemicals and biofuels replacing industrial synthesis chemistry.
