The minimum quantum requirement for photosynthesis under optimal conditions is about nine. Thus, the energy used is 9 × 50, or 450 kcal per mole of oxygen evolved.
How much ATP is used in photosynthesis?
Glucose combines with oxygen (oxidation), forming carbon dioxide, water and 38 molecules of ATP.
Do you need energy for photosynthesis?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. … The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.
How many ATP make glucose in photosynthesis?
A G3P molecule contains three fixed carbon atoms, so it takes two G3Ps to build a six-carbon glucose molecule. It would take six turns of the cycle, or 6 CO2start text, C, O, end text, start subscript, 2, end subscript, 18 ATP, and 12 NADPH, to produce one molecule of glucose.
How is ATP used in photosynthesis?
ATP is an important source of energy for biological processes. Energy is transferred from molecules such as glucose, to an intermediate energy source, ATP. … In photosynthesis energy is transferred to ATP in the light-dependent stage and the ATP is utilised during synthesis in the light-independent stage.
What 4 things are needed for photosynthesis?
The process of photosynthesis
Photosynthesis takes place in the part of the plant cell containing chloroplasts, these are small structures that contain chlorophyll. For photosynthesis to take place, plants need to take in carbon dioxide (from the air), water (from the ground) and light (usually from the sun).
What energy is needed by photosynthetic organisms during the process of photosynthesis?
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.
Is chlorophyll needed for photosynthesis?
Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion.
Does photosynthesis require ATP?
Yes, photosynthesis requires ATP. The ATP is produced during the light reaction of photosynthesis by chemiosmosis, which is utilised in the dark reaction for the formation of carbohydrates.
How much ATP is produced in the light reactions of photosynthesis?
The light-dependent reactions can be summarized as follows: 12 H2O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll yields 6 O2 + 12 NADPH + 18 ATP.
How is ATP made in the chloroplast?
The chloroplast adenosine triphosphate (ATP) synthase is located in the thylakoid membrane and synthesizes ATP from adenosine diphosphate and inorganic phosphate at the expense of the electrochemical proton gradient formed by light-dependent electron flow.
