Does reduction of oxygen that forms water occur in photosynthesis?

no, it's during respiration


Does the reduction of carbon dioxide occur during photosynthesis?

Plants use carbon dioxide to produce oxygen, so yes


Generation of proton gradients across membranes occurs during what?

Generation of proton gradients across membranes occur during both photosynthesis and respiration. The reduction of oxygen which forms water occurs during respiration.Ê


Does the reduction of CO2 occur in respiration or photosynthesis?

photosynthesis respiration produces co2, uses o2 photosynthesis opposite


Why do plants less oxygen during the night?

Oxygen is created via the process of photosynthesis. Without sunlight, photosynthesis cannot occur on anything beyond stored energy, resulting in a large decrease in oxygen production.Ê photosynthesis stops at night


What does not occur in photosynthesis?

Release of oxygen does not occur.


What would happen if oxygen were not produced during photosynthesis?

If oxygen were not produced during photosynthesis then organisms could not perform cellular respiration. This means that they couldn't produce carbon dioxide which would make the plants unable to undergo photosynthesis.


How do processes of photosynthesis and cellular respiration work together?

Photosynthesis provides glucose and oxygen in order for cellular respiration to occur.


Where do light reactions occur in photosynthesis?

Only when there is the presence of oxygen.


Where oxidation and reduction takes place?

Oxidation of water occurs wherever there is photosynthesis. Plants and organisms that perform photosynthesis take in water and other minerals and convert them to sugar, but the conversion to sugar creates a biproduct of free oxygen. This oxygen then oxidizes the water.


Is carbohydrates a product of photosynthesis?

Hydrogen is an element that when bonded with oxygen, will produce water 'H20'. And therefore is not a product of photosynthesis. However as water is a reactant in photosynthesis, it can be considered that hydrogen is a necessary atom for photosynthesis to occur


What time did the tree give off oxygen?

During the daytime. The production of photosynthesis, which can only occur during daylight (usually 8am-6pm or so) releases oxygen as a bi-product. Therefore, oxygen is expelled from plants in the daytime, and CO2 is released during the night.
