Why is CO2 reduced in photosynthesis?

The process Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

How does CO2 level affect oxygen production in photosynthesis?

Terms in this set (23) How does CO2 level affect oxygen production? increasing CO2 production increases oxygen production. Greater flow of oxygen corresponds to a higher rate of photosynthesis. Why would it be hard to find the ideal light intensity if the temperature were very hot or cold.

What is the difference between CO2 and O2 CO2?

CO2 has slightly more mass than O2. The molecular weight of CO2 is 44 grams per mole, while the molecular weight of oxygen is 32 grams per mole. Although CO2 is heavier than O2, the gases do not separate into layers in the atmosphere. Convection and diffusion keep the various atmospheric gases mixed.

Why is CO2 compensation point low in C4 plants?

The reason for low compensation value forC4 plants is the greater efficiency of CO2 fixation through PEP-carboxylase. The optimum CO2 concentration for C4 plants is 360 ppm and C3 plants, it is 450 ppm.

What is the advantage of the C4 pathway when CO2 concentrations are low?

Water Loss Plants that perform C4 photosynthesis can keep their stomata closed more than their C3 equivalents because they are more efficient in incorporation CO2. This minimizes their water loss.

Which of the following is required to increase the intracellular concentration of CO2?

During the C4 pathway, when the C4 acid from the mesophyll cells is broken down in the bundle sheath cells, it releases CO2 this results in increasing the intracellular concentration of CO2.

Which process does not occur in C4 plants?

In C4 plants photorespiration does not accur because they have a mechanism that increases the concentration of CO2at the enzyme site. This takes place when the C4 acid from the mesophyll. is broken down in the bundle sheath cells to release CO2 .

When CO2 is limiting in the atmosphere the rate of photosynthesis does not decrease in C4 plants?

CO2 concentration of the atmosphere is 360 ppm. It is a limiting factor for C3 as the available CO2 concentration is lower than the optimum for photosynthesis. Increase in its concentration upto 0.05% increases the rate of photosynthesis in most C3 plants.

Which of the following factor does not have direct effect on photosynthesis?

(b) The number of stomata. Photosynthesis is affected by light, temperature, water, and CO2. Stomata affect the process of transpiration and do not affect photosynthesis.

What are the factors affecting the photosynthesis?

The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.

Which one is not affect the rate of photosynthesis?

Temperature and rate of photosynthesis Although the light dependent reactions of photosynthesis are not affected by changes in temperature, the light independent reactions of photosynthesis are dependent on temperature. They are reactions catalysed by enzymes.

Why does the rate of photosynthesis not increase beyond a point even if the light intensity is increased?

Light intensity Without enough light, a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis , until some other factor – a limiting factor – becomes in short supply.

At what temperature do most plants stop photosynthesis?

104 degrees Fahrenheit

What color of light will maximize the rate of photosynthesis?

The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.

In which Colour of light photosynthesis is maximum and minimum?

Maximum absorption of light by chlorophyll a occurs in red and blue regions of the absorption spectrum. So that, the rate of photosynthesis is maximum in red and blue light of the visible spectrum. Minimum photosynthesis takes place in the green light.
