What best represents the relationships between the light reactions and the Calvin cycle?
Difference:The Calvin cycle converts carbon dioxide to carbohydrate.CO2 --------> (CH2O)This process requires an energy source and a hydrogen source, as well as carbon dioxide.The energy source is ATP. The hydrogen source is NADPH.Both of these substances are produced by the light-dependent reactions.For more details search this site for "calvin cycle", "light dependent" and "light independent".RELATIONSHIP:The light reactions and the Calvin cycle are both stages of photosynthesis. The light reactions (photosystems) produce NADPH, ATP, and Oxygen gas. The oxygen is released as a waste product but the NADPH and ATP enter the Calvin cycle, which produces a simple sugar moleculeSee related link and questions
Cells harvest energy from food molecules by what?
when oxygen is present pyruvant and NADH are used to make a large amount of ATP. this process is called aerobic respiration.
Uses energy from sunlight to make food molecules?
Phototroph or photoautotroph...basically plants and photosynthetic bacteria
To produce 4 molecules of sugar what would a plant need?
The production of one molecule of glucose needs 6 molecules of carbon dioxide, 6 molecules of water and some light energy. To make 4 molecules thus we'd need 24 carbon dioxides, 24 waters, and four times as much energy. Chlorophyll must also be present.
Explain what happens when sunlight hits a chlorophyll molecule?
As the sunlight hits the chlorophyll molecules sunlight is absorbed by a molecule of chlorophyll electrons in the molecule interact with photons of light and are raised to a higher energy level. The electrons are passed from one molecule to another in an electron transport chain producing ATP and NADPH. In case you don't know ATP is what cells mainly use for energy and NADPH is use as an electron carrier.Light energy is transferred to the electrons inthe chlorophyll molecule, raising the energy of theseelectrons. These high-energy electrons make photosynthesiswork.100% correct answer. Got it from answer book :D. You might want to change some words though since I got it straight from answer book...Its 9th grade biology btw
What provides energy to make photosynthesis work?
The molecules ATP and NADPH+
Which is the role of a photosystem I in the light reactions?
To make energy-carrier molecules like NADPH
Which is a role of photosystem 1 in the light reactions?
to make energy-carrier molecules like NADPH Apex
Where does the energy come from to make NADPHin the light reactant?
The energy to make NADPH in the light reactions of photosynthesis comes from sunlight. Light energy is absorbed by chlorophyll molecules in the chloroplasts of plant cells, which triggers a series of reactions that ultimately produce NADPH.
What is the reaction that requires direct energy of sunlight to make energy carrier molecules?
Photosynthesis is the reaction that requires direct energy from sunlight to produce energy carrier molecules like ATP and NADPH in plants.
The energy acquired in the light-dependent reaction is used in the light-independent reaction to build glucose molecule show is this energy transferred from light-dependent to light-independent react?
The energy acquired in the light-dependent reaction is stored in the form of ATP and NADPH molecules. These high-energy molecules are then used in the light-independent reaction (Calvin Cycle) to convert carbon dioxide into glucose. The ATP and NADPH transfer their stored energy to the Calvin Cycle enzymes, facilitating the conversion of carbon dioxide into glucose.
Where does the energy come from to make nadph in the lighte reactions?
from energy used in light.
How many ATP molecules can be produced from NA DH?
This question doesn't make sense because ATP molecules are independent from NADPH molecules. The only reason they are similar is because they are both energy carriers that help power the Calvin Cycle in Photosynthesis.
Photosystems light reactions?
Photosystems are protein complexes in the thylakoid membrane that are involved in the light reactions of photosynthesis. They capture light energy and convert it into chemical energy in the form of ATP and NADPH. There are two main photosystems in the thylakoid membrane, Photosystem I and Photosystem II, which work together to drive the conversion of light energy into chemical energy.
Which is role of photosystem in the light reactions?
to make energy-carrier molecules like NADPH Apex
This reaction requires direct energy of sunlight to make energy carrier molecules?
This is a description of photosynthesis, the process by which plants and other organisms convert sunlight into chemical energy in the form of energy carrier molecules like ATP and NADPH. Photosynthesis is essential for producing food and oxygen in many organisms.
What is the purpose of light reactions?
The purpose of light reactions in photosynthesis is to capture and convert light energy into chemical energy in the form of ATP and NADPH molecules. These energy-rich molecules are then used in the subsequent dark reactions to synthesize glucose and other carbohydrates.
