How does the electron transport chain work in photosynthesis?

How does the electron transport chain work in photosynthesis?

Chlorophyll, which is present in the photosystems, soaks up light energy. The energized electrons are then used to make NADPH. The electron transport chain is a series of molecules that accept or donate electrons easily. When hydrogen ions move through the protein and down the electron transport chain, ATP is created.

What is electron transport in photosynthesis?

Photosynthetic electron transport describes the process of light-induced electron transport for generating chemical energy and reducing equivalents in phototrophic organisms.

How do electrons move through the light reactions of photosynthesis?

The light reactions of photosynthesis use energy from photons to generate high-energy electrons (Figure 19.2). These electrons are used directly to reduce NADP+ to NADPH and are used indirectly through an electron-transport chain to generate a proton-motive force across a membrane.

How do electrons flow during photosynthesis?

The pathway of electron flow starts at photosystem II, which is homologous to the photosynthetic reaction center of R. Plastoquinone carries electrons from photosystem II to the cytochrome bf complex, within which electrons are transferred to plastocyanin and additional protons are pumped into the thylakoid lumen.

What are the electron carriers in photosynthesis and cellular respiration?

There are two types of electron carriers that are particularly important in cellular respiration: NAD +start superscript, plus, end superscript (nicotinamide adenine dinucleotide, shown below) and FAD (flavin adenine dinucleotide). Chemical structures of NAD+ and NADH.

What are the two electron carriers in photosynthesis?

The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH.

What are the 3 electron carriers?

Oxidation-reduction reactions always happen in matched pairs; no molecule can be oxidized unless another is reduced.

  • Flavin Adenine Dinucleotide. Flavin adenine dinucleotide, or FAD, consists of riboflavin attached to an adenosine diphosphate molecule.
  • Nicotinamide Adenine Dinucleotide.
  • Coenzyme Q.
  • Cytochrome C.

What are the two end products of photosynthesis?

Glucose and oxygen are the final products of photosynthesis.

What products are created by the process of photosynthesis?

The products of photosynthesis are glucose and oxygen. Although the hydrogen atoms from the water molecules are used in the photosynthesis reactions, the oxygen molecules are released as oxygen gas (O2).

What is the raw materials and end products of photosynthesis?

Photosynthesis is the conversion of light energy into chemical energy by living organisms. The raw materials are carbon dioxide and water; the energy source is sunlight; and the end-products are oxygen and (energy rich) carbohydrates, for example sucrose and starch.

What are the end products of this process?

During the process of photosynthesis, Carbon dioxide and Water combine in the presence of Sunlight and Chlorophyll to produce Carbohydrates (glucose) and Oxygen. Thus, the end products of photosynthesis are Carbohydrates(glucose) and Oxygen.

What is the raw material What are the end products?

Photosynthesis is the process when plants use energy from the sunlight to produce glucose from carbon dioxide and water. Carbon dioxide, water and sunlight are the raw materials of photosynthesis. Oxygen and glucose are the products. Please mark as brainliest.

What are the two main by products and the raw materials?

Answer. Answer: The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.

What are the raw materials and end products of glycolysis?

Answer. Answer: Glycolysis starts with one molecule of glucose and ends with two pyruvate (pyruvic acid) molecules, a total of four ATP molecules, and two molecules of NADH.

Which of the following is the key product of glycolysis?

pyruvic acid

What are the raw materials used in electron transport chain?

Glucose is the molecule that every cell in your body must have in order to function. It is the raw material that drives a multistep process called cellular respiration.

What raw materials are consumed in glycolysis?

Glycolysis Is an Energy-Conversion Pathway in Many Organisms Two molecules of ATP are consumed per molecule of glucose in these reactions, which are the prelude to the net synthesis of ATP.

What is the starting materials or raw materials in respiration?

ANSWER : Oxygen and Glucose are the two main raw materials that are needed in cellular respiration. This respiration is a type of respiration in which the glucose that we take in is converted into energy as ATP.

How many ATP is produced in glycolysis?


Does glycolysis produce 2 or 4 ATP?

During glycolysis, one glucose molecule is split into two pyruvate molecules, using 2 ATP while producing 4 ATP and 2 NADH molecules.

Where is this energy stored in glucose?

Energy is stored in the chemical bonds of the glucose molecules. Once glucose is digested and transported to your cells, a process called cellular respiration releases the stored energy and converts it to energy that your cells can use.

How does glucose become energy?

The transformation of glucose into energy occurs in one of two ways: with oxygen or without it. Glucose is converted to energy with oxygen in the mitochondria — tiny bodies in the jellylike substance inside every cell. This conversion yields energy (ATP, heat) plus water and carbon dioxide — a waste product.
