Does photosynthesis produce 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.
How do you get 38 ATP from glucose?
There is a theoretical maximum of 38 ATP produced from a single glucose molecule: 2 NADH produced in glycolysis (3 ATP each) + 8 NADH produced in Krebs cycle (3 ATP each) + 2 FADH2 produced I don’t know where (2 ATP each) + 2 ATP produced in the Krebs cycle + 2 ATP produced in glycolysis = 6 + 24 + 4 + 2 + 2 = 38 ATP.
How much ATP does 1 glucose molecule create?
Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
What is it called when ATP becomes ADP?
The Nature of ATP | Back to Top A cartoon and space-filling view of ATP. When the terminal (third) phosphate is cut loose, ATP becomes ADP (Adenosine diphosphate; di= two), and the stored energy is released for some biological process to utilize.
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.
Why do plants need ATP?
The process of cellular respiration allows plants to break down glucose into ATP. The ATP provides the energy they need to carry out various functions. Although plants use photosynthesis to produce glucose, they use cellular respiration to release energy from the glucose.
What is Nadph and ATP?
In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.
What is the role of ATP 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ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell.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 the major difference between ADP and ATP?
Explanation: Adenosine triphosphate, ATP , has three phosphate groups, hence the name with “tri-“. Adenosine diphosphate on the other hand, ADP , has only two phosphate groups, and so has the prefix “di-“. So, ATP has one extra phosphate group than ADP .
How much ATP is used in photosynthesis?
Figure 1). This gives one O2 molecule and two NADPH molecules. Three ATP molecules will be made, provided photosystem I recycles one electron in order to contribute two protons to the proton motive force.
What are the rules of ATP and Nadph in photosynthesis?
What are the roles of ATP and NADPH in photosynthesis? Both of these molecules carry energy; in the case of NADPH, it has reducing power that is used to fuel the process of making carbohydrate molecules in light-independent reactions.

What are the roles of ATP and Nadph in photosynthesis?
So in summary, there are two main roles of NADPH and ATP: (1) they tie the light dependent reactions and the light independent reactions together and (2) they act as sources of energy to take the energy from the sun to the light independent reactions to make the plants food.
What is the source of energy for ATP?
Adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.
What two main products result from photosynthesis?
Photosynthesis is the name given to the set of chemical reactions performed by plants to convert energy from the sun into chemical energy in the form of sugar. Specifically, plants use energy from sunlight to react carbon dioxide and water to produce sugar (glucose) and oxygen.
What is the difference between glucose and ATP?
Answer: In terms of energy there is a difference between glucose and ATP. The stored form of energy in the body is glucose and when the body requires energy glucose is broken down to obtain energy in the form of ATP. The body stores energy in the form of glucose and the cells use energy by breaking the bonds of ATP.
What is the net charge of ATP?
Here’s what it looks like chemically. Each phosphate is a PO4 (oxygen has a charge of -2 and there are 4 of them, for a total of -8, and P has a charge of +5, so the net charge on the phosphate group is -3.
Why do we use 36 ATP instead of 38?
During citric acid cycle, 36 ATP molecules are produced. So, all together there are 38 molecules of ATP produced in aerobic respiration and 2 ATP are formed outside the mitochondria. Thus, option A is correct.
What foods produce ATP?
The ATP your body produces and stores comes from the oxygen you breathe and the food you eat. Boost your ATP with fatty acids and protein from lean meats like chicken and turkey, fatty fish like salmon and tuna, and nuts.
How is ADP converted to ATP?
ADP is combined with a phosphate to form ATP in the reaction ADP+Pi+free energy→ATP+H2O. The energy released from the hydrolysis of ATP into ADP is used to perform cellular work, usually by coupling the exergonic reaction of ATP hydrolysis with endergonic reactions.
How is glucose converted to ATP?
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Where is energy stored in glucose?
The energy in glucose is stored primarily in the carbon-carbon and carbon-hydrogen bonds. In fact, anything with carbon-carbon and carbon-hydrogen bonds stores energy. Other common examples include gasoline, coal, and fat.
What would be the net gain of ATP from the breakdown of 10 molecules of glucose under aerobic conditions?
360 would be the net gain of ATP from the breakdown of ten molecules of glucose under aerobic conditions.
How many ATP are produced in the Krebs cycle?
The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle).
What process makes ATP?
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).
What is the function of Nadph and ATP?
The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle. In another form of the light reactions, called cyclic photophosphorylation, electrons follow a different, circular path and only ATP (no NADPH) is produced.
Why energy is stored in form of ATP?
Cellular energy is primarily trapped and stored in the form of adenosine triphosphate or ATP. To trap energy released from exergonic catabolic chemical reactions, the cell uses some of that released energy to attach an inorganic phosphate group on to adenosine diphosphate (ADP) to make adenosine triphosphate (ATP).
