The part of the solar spectrum used by plants has an estimated mean wavelength of 570 nm; therefore, the energy of light used during photosynthesis is approximately 28,600/570, or 50 kcal per einstein.
How much ATP is produced by photosynthesis?
Three ATP molecules will be made, provided photosystem I recycles one electron in order to contribute two protons to the proton motive force.
Does photosynthesis produce or use energy?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
How do plants produce ATP?
Plants, through the process of photosynthesis, make use of the sunlight to energise and generate glucose through the available water and carbon dioxide. Through cellular respiration, pyruvate in turn gives ATP (adenosine triphosphate). …
Does photosynthesis generate ATP?
The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.
Does photosynthesis produce oxygen?
In plants, algae, and cyanobacteria, photosynthesis releases oxygen. This is called oxygenic photosynthesis and is by far the most common type of photosynthesis used by living organisms. … These nutrients are oxidized to produce carbon dioxide and water, and to release chemical energy to drive the organism’s metabolism.
What do plants do with extra glucose?
What do plants do with the extra glucose that they produce? They use it to produce carbohydrates , proteins, and fats. These are used as sources of stored energy.
Is it true or false carbon dioxide is released during photosynthesis?
From the above information we have found that carbon dioxide is not released during photosynthesis. Instead of it oxygen is released.
Do plants use ATP?
In addition to mitochondrial ATP synthesis, plants can also make ATP by a similar process during the light reactions of photosynthesis within their chloroplasts. … This is an especially vital source of ATP for plants because ATP is also needed for them to synthesize glucose in the first place.
What is the process of ATP production called?
The process human cells use to generate ATP is called cellular respiration. It results in the creation of 36 to 38 ATP per molecule of glucose. … The two ATP-producing processes can be viewed as glycolysis (the anaerobic part) followed by aerobic respiration (the oxygen-requiring part).
Why is energy from ATP used in photosynthesis?
ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Animals store the energy obtained from the breakdown of food as ATP. Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules.
What is Pi in photosynthesis?
The PI (or photosynthesis-irradiance) curve is a graphical representation of the empirical relationship between solar irradiance and photosynthesis. A derivation of the Michaelis–Menten curve, it shows the generally positive correlation between light intensity and photosynthetic rate.
