During reduction, 3-PGA reacts with ATP and NADPH. ... The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2. In the chemical equation for photosynthesis, carbon dioxide and water are converted to glucose and oxygen.

What do NADPH and ATP reduce?

These electrons are used to produce NADPH as well as ATP in a series of reactions called the light reactions because they require light. NADPH and ATP formed by the action of light then reduce carbon dioxide and convert it into 3-phosphoglycerate by a series of reactions called the Calvin cycle or the dark reactions.

Which is required for light-independent reactions in photosynthesis to occur?

The ultimate goal of the light-independent reactions (or Calvin cycle) is to assemble a molecule of glucose. This is the part of photosynthesis that requires the CO2 the plant gets from the air. Essentially, the plant needs the carbon from the CO2 to create the building blocks for glucose.

What reaction uses ATP and NADPH?

The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.

What occurs during the light-independent reactions of photosynthesis quizlet?

The light-dependent reactions require light and water, occur in the thylakoids, and produce ATP and NADPH. The light-independent reactions require carbon dioxide, occur in the stroma, and produce high-energy sugars.

What is one role of ATP in the light-independent reaction of photosynthesis quizlet?

What is one role of ATP in the light-independent reaction of photosynthesis? ATP supplies the energy to produce glucose and other carbohydrates. ... In the chemical equation for photosynthesis, carbon dioxide and water are converted to glucose and oxygen.

What are the 3 primary factors that affect the rate of photosynthesis?

Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
  • Light intensity. Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide. ...
  • Carbon dioxide concentration. ...
  • Temperature.

How is ADP converted to ATP?

ADP is converted to ATP for the storing of energy by the addition of a high-energy phosphate group. The conversion takes place in the substance between the cell membrane and the nucleus, known as the cytoplasm, or in special energy-producing structures called mitochondria.

How is energy released from a molecule of ATP?

When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). ... This free energy can be transferred to other molecules to make unfavorable reactions in a cell favorable.

What are the roles of ATP and NADPH in photosynthesis?

ATP and NADPH are energy storage and electron carrier/donor molecule. Both ATP and NADPH are used in the next stage of photosynthesis. The chlorophyll molecule regains the lost electron from a water molecule through a process called photolysis, which releases dioxygen (O2) molecule.

What raw materials are used in light-independent reactions?

Answer: Raw materials are Carbon dioxide and water; light reaction happens in plants.

How does light-dependent reactions produce ATP?

In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. ... The energy generated by the hydrogen ion stream allows ATP synthase to attach a third phosphate to ADP, which forms a molecule of ATP in a process called photophosphorylation.

What is the process of photorespiration?

Photorespiration is the process of light-dependent uptake of molecular oxygen (O2) concomitant with release of carbon dioxide (CO2) from organic compounds. The gas exchange resembles respiration and is the reverse of photosynthesis where CO2 is fixed and O2 released.

How much ATP and NADPH is used in Calvin cycle?

The Calvin cycle uses 18 ATP and 12 NADPH molecules to produce one glucose molecule.

How many ATP are used in dark reaction?

Glyceride -3- phosphate uses 3 ATP molecules to convert into ribulose-1,5- biphosphate which enters a new cycle of dark reaction by combining with the incoming CO2.

How many ATP are produced in glycolysis?

During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi --> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate.

What enzyme breaks down ATP?

ATPases are a group of enzymes that catalyze the hydrolysis of a phosphate bond in adenosine triphosphate (ATP) to form adenosine diphosphate (ADP). They harness the energy released from the breakdown of the phosphate bond and utilize it to perform other cellular reactions.

What process produces the most ATP?

Explanation: The electron transport chain generates the most ATP out of all three major phases of cellular respiration. Glycolysis produces a net of 2 ATP per molecule of glucose.

How much energy is released when ATP is broken down?

The hydrolysis of one ATP molecule releases 7.3 kcal/mol of energy (∆G = −7.3 kcal/mol of energy).

What are some examples of cell processes that use ATP?

ATP is consumed for energy in processes including ion transport, muscle contraction, nerve impulse propagation, substrate phosphorylation, and chemical synthesis.

What is the major difference between ADP and ATP?

ATP is adenosine triphosphate and contains three terminal phosphate groups, whereas ADP is adenosine diphosphate and contains only two phosphate groups. ADP is produced on hydrolysis of ATP and the energy released in the process is utilised to carry out various cellular processes.

What happens when ATP is converted to ADP quizlet?

A phosphate is removed from an ATP molecule in order to provide energy for the cell. Thus, the ATP molecule turns into an ADP molecule. We eat food which gives us energy to add another phosphate group to the ADP molecule, turning it into an ATP molecule. The cycle then begins again.

What increases the rate of photosynthesis?

Light intensity

Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.

Does photosynthesis continues to increase with temperature?

Although the light dependent reactions of photosynthesis are not affected by changes in temperature, the light independent reactions of photosynthesis are dependent on temperature. They are reactions catalysed by enzymes. As the enzymes approach their optimum temperatures the overall rate increases.

What are the 4 factors that affect the rate of photosynthesis?

What factor most affects the rate of photosynthesis? The main variables which affect photosynthesis are light, water, CO2 concentration and temperature.
