THE CALVIN CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following affects the rate of photosynthesis?
A
amount of water
B
carbon dioxide concentration
C
temperature
D
all of these
Explanation: 

Detailed explanation-1: -The factors which affect photosynthesis are light, water, carbon dioxide, temperature, chlorophyll and availability of nutrients.

Detailed explanation-2: -The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.

Detailed explanation-3: -Photosynthesis is affected by light, temperature, water, and CO2. Stomata affect the process of transpiration and do not affect photosynthesis.

Detailed explanation-4: -As with any other enzyme-controlled reaction, the rate of photosynthesis is affected by temperature. At low temperatures, the rate of photosynthesis is limited by the number of molecular collisions between enzymes and substrates. At high temperatures, enzymes are denatured .

Detailed explanation-5: -Answer: Light intensity, carbon dioxide concentration, and temperature are the three main limiting factors affecting photosynthesis.
