What is the first phase of photosynthesis?

The first stage of photosynthesis is called the 'Light Dependant' stage or the photolysis of water. this is when light enters the cell and splits water into hydrogen and oxygen. The oxygen is then released into the atmosphere and the hydrogen is picked up by the hydrogen acceptor NADP becoming reduced NADPH2 which is then used for the next stage of photosynthesis.

Where do the hydrogen atoms in glucose come from?

Glucose is a product of the process of photosynthesis. The compounds used for this process is CO2 and H2O. So H comes from water.

What supplies the process during the initial process of photosynthesis that drives ATP synthesis?


What products of the light reaction are used in the light independent stage of photosynthesis?


How energy and hydrogen sequestered in the light reactions of photosynthesis are used to drive the dark reactions of photosynthesis?

You should ask Mr. Newberry. Hahaha

What gas is required to start stage 3 of photosynthesis?

Oxygen is used where as in photo-respiration Carbon dioxide is used. Oxygen used in photosynthesis comes out as carbon dioxide as a bi-product.

What is the function of water in photosynthesis?

In order to successfully answer this question, we need to establish the symbol equation for photosynthesis: 6CO2 + 6H2O ------ C6H12O6 + 6O2 carbon dioxide + water (go to) glucose + oxygen Water is necessary to balance this equation, and to provide the hydrogen that is required for the energy.

What is it called when light energy from the sun is captured and used to split water into hydrogen and oxygen?


What chemical substances are used during the manufacture of organic molecules in photosynthesis?

Hydrogen, ATP and CO2

What are the 2 main reactions in photosynthesis?

Photosynthesis happens in two stages, also called reactions. The first stage is the light-dependent stage. In this stage light energy is absorbed by chlorophyll and converted into chemical energy, and water is split to produce hydrogen. The unwanted oxygen from the water is released. The second stage is the light-independent stage. In this stage the chemical energy and the hydrogen from the first stage are used to convert carbon dioxide into carbohydrates, such as glucose. More details can be found on this site by searching for photosynthesis.

What will happen when you separate H20?

This is the trick known as photosynthesis, where the oxygen is split from the hydrogen and expelled as a waste gas. The hydrogen is available and used by the plant to build its tissues.

What is the bi-product of water and air from photosynthesis?

oxygen and water.oxygen from water when it splits into hydrogen and oxygen because only the hydrogen is used, and water from carbon dioxide that combines with hydrogen to make a carbohydrate,
