The molecule that serves as the source of the gas released as a by-product of the light-dependent reactions of photosynthesis is water (H₂O). During these reactions, water is split through a process called photolysis, leading to the release of oxygen (O₂) gas. This oxygen is then released into the atmosphere.

Which molecule is broken down by light absorbed in LDR?

Water is the molecule that is broken down by light absorbed in the Light-Dependent Reactions (LDR) of photosynthesis. This process results in the release of oxygen as a byproduct.


How many molecules of O2 are released for every CO2 molecule fixed by photosynthesis?

For every molecule of CO2 fixed during photosynthesis, one molecule of O2 is released. This process occurs during the light-dependent reactions of photosynthesis when water is split to release oxygen as a byproduct.


The source of oxygen produced during photosynthesis is?

The source of oxygen produced during photosynthesis is water. During the light-dependent reactions of photosynthesis, water molecules are split into oxygen, protons, and electrons, releasing oxygen as a byproduct.


Name a gas released as by product of the light dependent reactions of photosynthesis?

Oxygen is released as a by product of photosynthesis.


What molecule is energy captured for photosynthesis?

chlorophyll


What molecule is recycled between the Calvin cycle and the light dependent reactions during photosynthesis?

The molecule recycled between the Calvin cycle and the light-dependent reactions is adenosine triphosphate (ATP). ATP is produced in the light-dependent reactions and then utilized in the Calvin cycle to provide energy for the synthesis of sugars.


What part of the water molecule is used during photosynthesis?

The hydrogen atoms in the water molecule are used during photosynthesis. Water molecules are split into oxygen, protons, and electrons during the light-dependent reactions in photosynthesis.


Water is the source of what product of photosynthesis during the light dependent reactions of photosynthesis?

# photosynthesis 2. Water is the source of hydrogenduring the light dependent reaction of photosynthesis. Water is split into hydrogen and oxygen. The oxygen is released into the atmosphere and the hydrogen is transferred to a carrier molecule called NADP, to produce NADPH. The NADPH is then used in the light independent reaction to reduce carbon dioxide to carbohydrate. See my answer to this question on WikiAnswers: What connects the light dependent reaction to the light independent reaction?


What are the waste products in photosynthesis?

The waste product of photosynthesis is oxygen, which is released into the atmosphere as a byproduct of the light-dependent reactions. This oxygen is crucial for many organisms, including humans, as it is essential for respiration.


What is the name of the molecule that carries electrons from the light dependent reactions to the Calvin cycle?

The molecule that carries electrons from the light-dependent reactions to the Calvin cycle is called NADPH (nicotinamide adenine dinucleotide phosphate). NADPH is produced during the light-dependent reactions in photosynthesis and then used in the Calvin cycle to help fix carbon dioxide into sugars.


What molecule is split during the light reactions of photosynthesis to release oxygen?

Water molecule is split during the light reactions of photosynthesis to release oxygen.


How does the heat content of the reaction change in the process of photosynthesis when a glucose molecule is formed?

The heat content of the reaction in photosynthesis where a glucose molecule is formed is endothermic, meaning energy is absorbed. This is because sunlight is absorbed during the light-dependent reactions to produce ATP and NADPH, which are then used in the light-independent reactions to form glucose. Overall, photosynthesis is an energy-storing process.
