The substance that initially traps solar energy in photosynthesis is

Which of the following is a substance that initially traps solar energy in photosynthesis?

A. Chlorophyll

What is the energy that is captured during photosynthesis?

light energy

In which plant structure does photosynthesis primarily occur?


Where did the ATP come from in photosynthesis?

During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. The light energy is intercepted by chlorophyll molecules on the granal stacks. Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP.

What is the function of ribulose bisphosphate during photosynthesis?

Ribulose bisphosphate is a compound that plays an important role in the Calvin-Benson cycle. Layman’s explanation: The process of incorporating carbon dioxide into cell carbon is called carbon fixation. Ribulose bisphosphate is found in the stroma of a chloroplast where the Calvin-Benson cycle takes place.

Why are plant leaves green quizlet?

Leaves are green because of a pigment known as chlorophyll. The chlorophyll masks the colors of any other pigments in the leaf cells. In the autumn, chlorophyll breaks down revealing other colors present in the leaf. You just studied 15 terms!

What is a photolysis?

Photolysis (also called photodissociation and photodecomposition) is a chemical reaction in which an inorganic chemical (or an organic chemical) is broken down by photons and is the interaction of one or more photons with one target molecule.

What are two stages in photosynthesis?

Figure: The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.

Where is carbon dioxide and water stored before photosynthesis?


What is the purpose of photosynthesis?

It’s not oxygen production. The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet’s living systems are powered by this process.

What is the first step in photosynthesis?

Absorption of light

The first step in photosynthesis is the absorption of light by chlorophylls that are attached to the proteins in the thylakoids of chloroplasts. The light energy absorbed is then used to remove electrons from an electron donor like water, forming oxygen.

What type of reaction is photosynthesis?

endothermic reaction

Does photosynthesis produce ATP?

The stages of photosynthesis

The light-dependent reactions take place in the thylakoid membrane. They require light, and their net effect is to convert water molecules into oxygen, while producing ATP molecules—from ADP and Pi—and NADPH molecules—via reduction of NADP+.

Can photosynthesis occur without ATP?

In addition to mitochondrial ATP synthesis, plants can also make ATP by a similar process during the light reactions of photosynthesis within their chloroplasts. … Without a photosynthetic source of ATP, plants would be using up their ATP to make glucose, and then using up glucose to make ATP, a “catch-22” situation.
