How is light energy transformed into chemical energy during photosynthesis?

Answer 1

Photophosphorylation is the process of creating ATP using a Proton gradient created by the Energy gathered from sunlight. The process of creating the Proton gradient resembles that of the electron transport chain of Respiration. But since formation of this proton gradient is light-dependent, the process is called Photophosphorylation.

Chemiosmosis - Chemiosmosis is the process of using Proton movement to join ADP and Pi. This is accomplished by enzymes called ATP synthases or ATPases. The CF1-ATPase of the Thylakoid membrane is shown on the left (DIAGRAM IN LINK). As protons pass through this enzyme ADP and Pi are joined to make ATP. The movement of the Protons through this enzyme provides the Energy needed to make ATP

Answer 2

Light is captured by the chlorophyll in the chloroplasts of plant cells. More specifically:

Each thylakoid membrane is made of photosystem I and II. Light hits photosystem II first, and the plant uses a water molecule and breaks it up. The released e- is used to boost it up to the ETC (electron transport chain) where ATP is produced. The energy is moved to photosystem I, which absorbs a different wavelength of light. It falls down the ETC to form NADP+ reluctase and ATP, which is then used by the Calvin's Cycle. The Calvin cycle uses CO2 from the envioroment and uses the NADP+ and ATP created by the light reaction to form NADPH and sugar through carbon fixation and reduction.

Thus, light energy is converted into chemical energy (glucose).

Answer 4

In most living things, energy is created in the form of ATP. In plants, this energy is taken from the light, and ATP is made alongside NADPH2.

Answer 5

because when the sun light hits the plant the sugar makes chemical energy.

Answer 6

it gives food:)i am just &years old !
