what are the inputs to the calvin cycle

What Are The Inputs To The Calvin Cycle?

1. For each of the two main stages of photosynthesis, identify the inputs. Inputs of the light reactions are light and water, and ADP, P, and NADP+ from the Calvin cycle. Inputs of the Calvin cycle are CO2, and ATP and NADPH from the light reactions.

What are the inputs to the Calvin cycle where do they come from?

The inputs to the Calvin cycle are CO₂, ATP, and NADPH. The CO₂ comes from the atmosphere around the plant, and the ATP and NADPH come from the light-dependent reaction.

What are the inputs into the Calvin cycle and what are the outputs?

In the Calvin cycle, the energy outputs from the light reactions (ATP and NADPH) are used to power the conversion of CO2 into the sugar G3P. As ATP and NADPH are used, they produce ADP and NADP+, respectively, which are returned to the light reactions so that more ATP and NADPH can be formed. You just studied 13 terms!

What goes into and out of the Calvin cycle?

The Calvin cycle is a process that plants and algae use to turn carbon dioxide from the air into sugar, the food autotrophs need to grow. … The Calvin cycle has four main steps: carbon fixation, reduction phase, carbohydrate formation, and regeneration phase.

What is the initial input in the Calvin cycle?

What is the INITIAL carbon input in the Calvin cycle? The Calvin cycle begins with carboxylation which is the addition of carbon dioxide to the five carbon structure.

What are the three main inputs to the Calvin cycle?

The inputs to the Calvin cycle are CO₂, ATP, and NADPH. The CO₂ comes from the atmosphere around the plant, and the ATP and NADPH come from the light-dependent reaction.

What are the four inputs to the Calvin cycle needed to produce glucose?

The four inputs that are required to synthesize glucose during the Calvin cycle are carbon dioxide, ribulose-1, 5-bisphosphate (RUBP), nicotinamide adenine dinucleotide phosphate hydrogen (NADPH), and adenosine triphosphate (ATP).

What is the output product of the Calvin cycle?

The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.

How does Calvin cycle begin?

The Calvin cycle has three stages. In stage 1, the enzyme RuBisCO incorporates carbon dioxide into an organic molecule. In stage 2, the organic molecule is reduced. In stage 3, RuBP, the molecule that starts the cycle, is regenerated so that the cycle can continue.

What occurs in the Calvin cycle?

The Calvin cycle is part of photosynthesis, which occurs in two stages. In the first stage, chemical reactions use energy from light to produce ATP and NADPH. In the second stage (Calvin cycle or dark reactions), carbon dioxide and water are converted into organic molecules, such as glucose.

Does the Calvin cycle release oxygen?

The Calvin Cycle converts three water and three carbon dioxide molecules into one molecule of glyceraldehyde. The six left over oxygen atoms are released into the atmosphere where they are available for use in respiration.

What happens to cO2 in the Calvin cycle?

What happens to carbon dioxide molecules in the Calvin cycle reactions? carbon dioxide molecules are bonded together with the electrons and H’s from NADPH to form glucose. … cO2 goes in and O2 comes out. it helps to exchange them using simple diffusion.

Where does photosynthesis take place?

chloroplasts

In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

What provides electrons for the light reactions?

Light reactions occur when plants synthesize food from carbon dioxide and water, referring specifically to the part of energy production that requires light and water to generate electrons needed for further synthesis. Water provides the electrons by splitting into hydrogen and oxygen atoms.

What are the 3 inputs of photosynthesis?

In photosynthesis, water, carbon dioxide, and energy in the form of sunlight are inputs, and the outputs are glucose and oxygen.

What are the inputs of photosystem 2?

The input of photosystem II are light, water, ADP+P. The output of photosystem II is oxygen and ATP. It occurs in the inner surface of the grana of the thylakoid membrane.

What is the input for the light independent reactions or Calvin cycle )?

The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.

GoalConvert light energy into chemical energy
OutputNADPH, ATP, O2

Where does Calvin cycle occur?

stroma Understand Light Independent Reactions (Calvin Cycle) : Example Question #1. Where does the Calvin Cycle take place? Explanation: The Calvin Cycle (dark reactions) take place in the stroma of the chloroplasts, which is the aqueous space inside the organelle.

Where does the Calvin cycle occur quizlet?

Where does the Calvin Cycle occur? The Calvin Cycle occurs in the stroma, whereas the light reactions occur in the thylakoids.

Which molecule must enter the Calvin cycle continually?

RuBP

The Calvin cycle has three stages. In stage 1, the enzyme RuBisCO incorporates carbon dioxide into an organic molecule, 3-PGA. In stage 2, the organic molecule is reduced using electrons supplied by NADPH. In stage 3, RuBP, the molecule that starts the cycle, is regenerated so that the cycle can continue.

What is the main product of the Calvin cycle quizlet?

The product of the Calvin cycle is a triose-phosphate sugar that is either exported from the chloroplast or used to regenerate RUBP.

Is water produced in the Calvin cycle?

The production of water occurs during the carbon fixation reactions known as the Calvin-Benson cycle.

What source of energy is used in the Calvin cycle?

The Calvin cycle is also sometimes referred to as the “light independent” reactions of photosynthesis, since it is not powered directly by photons from the Sun. Instead, the Calvin cycle is powered by ATP and NADPH, which are created by harnessing the energy from photons in the light-dependent reactions.

What are the inputs and outputs of light reactions quizlet?

Light-dependent reactions convert solar energy into chemical energy in the form of NADPH and ATP. the input molecules are carbon dioxide and the output molecules are sugar, ADP, NADP+, and inorganic phosphate.

What are the inputs for the light reactions of photosynthesis?

Is light an input or output?

Input​ refers to the amount of energy put into a device, and ​ output​ refers to the amount of energy that comes out. A device may change the type of energy but not the amount. For example, a light bulb’s input energy is the form of electrical energy, and its output energy is in the form of light and heat.

What happens during the Calvin cycle quizlet?

In the Calvin cycle, carbon dioxide is incorporated into organic compounds, a process called carbon fixation. … In the light reactions, energy is absorbed from sunlight and converted into a chemical energy; in the Calvin cycle, carbon dioxide and chemical energy are used to form organic compounds.

What are the three phases of the Calvin cycle quizlet?

What are the three phases or steps of the Calvin Cycle? Fixation, reduction, and regeneration.

What is the primary function of the Calvin cycle?

The Calvin cycle uses the energy from short-lived electronically excited carriers to convert carbon dioxide and water into organic compounds that can be used by the organism (and by animals that feed on it). This set of reactions is also called carbon fixation. The key enzyme of the cycle is called RuBisCO.
