What are the high energy reactants of photosynthesis?
During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).
- Photosynthesis is the process plants use to make their own food.
- The reactants of photosynthesis are carbon dioxide and water.
What are the two high energy molecules used during photosynthesis?
Photosynthesis takes place in two stages: light dependent reactions and the Calvin cycle. Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2.
What is the high energy electron carrier in photosynthesis?
NADP+
NADP+ (nicotinamide adenine dinucleotide phosphate) – carrier molecule that transfers high-energy electrons from chlorophyll to other molecules. It accepts and holds two high-energy electrons and a hydrogen to become NADPH.
Which molecule is used up in photosynthesis?
The molecules that are used up in photosynthesis are water and carbon dioxide.
What is the energy source for photosynthesis?
the Sun
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
What is a high energy electron?
High Energy Electrons do mean the unstable electrons present in the biochemicals. These biochemicals are unstable because they’ve missed aromaticity ,their previous octet configuration or became radicals etc. therefore they have high Gibbs energy.
What are the master molecules in the process of photosynthesis?
The molecules that are used up in photosynthesis are water and carbon dioxide. During the light reactions of photosynthesis, plants use water.
Which molecules are needed for photosynthesis?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
What molecules go into photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
What are high energy molecules?
ATP. ATP (Adenosine Triphosphate) contains high energy bonds located between each phosphate group.
What are the roles of ADP ATP and NADP +/ NADPH in photosynthesis?
The forms of chemical energy made are NADPH and ATP (from their low energy forms of NADP+ and ADP). So basically the cell takes the light energy and turns it into usable energy in the forms of these two molecules. That is simple enough.
Why is glucose a high-energy molecule?
If you’ve heard it said that molecules like glucose have “high-energy” electrons, this is a reference to the relatively high potential energy of the electrons in their C−C and C−H bonds. Quite a bit of energy can be released when electrons in C−C and C−H bonds are shifted to oxygen.
What molecules carry these high potential energy?
What molecules carry these high potential energy electrons? NADH and FADH2 carry these high potential energy electrons.
Why is NADH higher energy than FADH2?
Correct answer: FADH2 produces less ATP then NADH because the electrons for FADH2 are dropped off at the second protein of the electron transport chain.
What is the source of energy for photosynthesis?
Photosynthesis – The Cell – NCBI Bookshelf During photosynthesis, energy from sunlight is harvested and used to drive the synthesis of glucose from CO2 and H2O. By converting the energy of sunlight to a usable form of potential chemical energy, photosynthesis is the ultimate source of metabolic energy for all biological systems.
Where do the light reactions of photosynthesis occur in a cell?
In eukaryotic cells, both the light and dark reactions of photosynthesis occur within chloroplasts—the light reactions in the thylakoid membrane and the dark reactions within the stroma. This section discusses the light reactions of photosynthesis, which are related to oxidative phosphorylation in mitochondria.
What is the ultimate source of metabolic energy for all organisms?
By converting the energy of sunlight to a usable form of potential chemical energy, photosynthesis is the ultimate source of metabolic energy for all biological systems. Photosynthesis takes place in two distinct stages. In the light reactions, energy from sunlight drives the synthesis of ATP and NADPH, coupled to the formation of O2 from H2O.
