Are the atoms in photosynthesis recycled?

Photosynthesis is the process by which green plants capture energy from sunlight and use it to make food molecules like glucose. … Energy cannot be recycled because it is used. Matter, in the forms of carbon, oxygen, and hydrogen, is continually recycled.

What happens to atoms in photosynthesis?

Photosynthetic organisms store the glucose (usually as starch) and release the oxygen gas into the atmosphere as waste. … Light energy is thus transformed into chemical energy, stored in the bonds which bind six atoms each of carbon and oxygen to twelve atoms of hydrogen – forming a molecule of glucose.

What happens to the oxygen atoms in photosynthesis?

In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.

What component in photosynthesis is not recycled?

The major component in photosynthesis that is not recycled and is readily available is sunlight.

What happens to the products of photosynthesis?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

What are end products of photosynthesis?

Though the final product of photosynthesis is glucose, the glucose is conveniently stored as starch. Starch is approximated as (C6H10O5)n, where n is in the thousands. Starch is formed by the condensation of thousands of glucose molecules.

How many oxygen atoms come out of photosynthesis?

How many oxygen atoms come in and come out of photosynthesis? 12 oxygen atoms come in. 12 oxygen atoms come out.

Where does the oxygen come from in photosynthesis?

The oxygen released during photosynthesis comes from the splitting of water during the light-dependent reaction. 3. Remember, the electrons lost from the reaction center in photosystem II must be replaced. The splitting of water serves to replace these lost electrons.

Do plants need oxygen for photosynthesis?

Yes, it is. Plants need oxygen to survive, and plant cells are constantly using oxygen. … Respiration in plants is like photosynthesis run backwards: instead of capturing energy by manufacturing sugars and releasing oxygen, cells release energy for their own use by breaking down sugars and using up oxygen.

Which molecules are recycled in photosynthesis?

The four substances recycled during photosynthesis and respiration are carbon dioxide, water, oxygen and glucose.

Which element is not recycled through an ecosystem by the process of photosynthesis and respiration?

– Energy is not recycled in the ecosystem. From one level to another level there is only 10% energy is further transfer and another 90% used in the process. So, the correct answer is ‘Energy’.

What 4 substances are recycled during photosynthesis and cellular respiration?

The four substances recycled during photosynthesis and respiration are carbon dioxide, water, oxygen and glucose.

What two main products result from photosynthesis?

Photosynthesis takes the energy of sunlight and combines water and carbon dioxide to produce sugar and oxygen as a waste product.
