Your question: What environmental factors might impact the rate at which the Calvin cycle occurs?

The amount of carbon dioxide that the plant can access affects the Calvin cycle. A higher concentration of carbon dioxide means that the rate of the photosynthesis process can increase. In addition, the temperature affects the cycle.

What are environmental factors that could 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.
IMPORTANT:  What is the value of environmental science?

What comes from the environment and is needed for the Calvin cycle to occur?

In plants, carbon dioxide (CO2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions where sugar is synthesized. The reactions are named after the scientist who discovered them, and reference the fact that the reactions function as a cycle.

What are three factors that affect the rate at which photosynthesis occurs?

Several factors can affect the rate of photosynthesis:

  • light intensity.
  • carbon dioxide concentration.
  • temperature.

How does the Calvin cycle benefit the environment *?

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. Every living thing on Earth depends on the Calvin cycle. Plants depend on the Calvin cycle for energy and food.

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.

How environmental factors such as light intensity and carbon dioxide levels can affect rates of photosynthesis?

As light intensity increases, the rate of photosynthesis will increase as long as other factors are in adequate supply. … If carbon dioxide and light levels are high, but temperature is low, increasing temperature will have the greatest effect on reaching a higher rate of photosynthesis.

What is the most important result 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.

What are the major events that occur during the light reaction in the photosynthesis stage?

During the light-dependent stage (“light” reactions), chlorophyll absorbs light energy, which excites some electrons in the pigment molecules to higher energy levels; these leave the chlorophyll and pass along a series of molecules, generating formation of NADPH (an enzyme) and high-energy ATP molecules.

How are the products produced in the light reactions used in the Calvin cycle?

In the Calvin cycle, carbon atoms from CO2​start text, C, O, end text, start subscript, 2, end subscript are fixed (incorporated into organic molecules) and used to build three-carbon sugars. … This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.

What five factors affect photosynthesis and its rate?

The environmental factors which can affect the rate of photosynthesis are carbon dioxide, light, temperature, water, oxygen, minerals, pollutants and inhibitors. 1. Effect of Carbon dioxide: Being one of the raw materials, carbon dioxide concentration has great effect on the rate of photosynthesis.

What factors affect the rate of photosynthesis quizlet?

Temperature, light intensity, carbon dioxide levels, water, oxygen and chlorophyll. The rate of photosynthesis increases as the temperature increases. However, the rate declines after the temperature reaches an optimal level (usually around 35 C). The rate of photosynthesis increases as light intensity increases.

What are the factors affecting photosynthesis Class 10?

The factors affecting rate of photosynthesis are: Temperature Intensity and wavelength of sunlight Carbon dioxide concentration Water

  • Temperature.
  • Intensity and wavelength of sunlight.
  • Carbon dioxide concentration.
  • Water.

How does the Calvin cycle relate to climate change?

During photosynthesis, molecules of carbon dioxide absorbed from the atmosphere enter into a series of chemical reactions known as the Calvin cycle. … The effect becomes more pronounced at cold temperatures, high light levels, and – importantly for climate scientists – higher concentrations of carbon dioxide.

What happens after the Calvin cycle?

After six turns of the Calvin cycle, two molecules of glyceraldehyde-3 phosphate can be combined to make a glucose molecule. … This means that to produce a single molecule of glucose, 18 ATP and 12 NADPH are consumed.

Which of the following occurs during the Calvin cycle?

During the Calvin cycle of photosynthesis, NADPH produced in the light reactions is oxidized, and carbon is reduced using the electrons from NADPH. The reduction of carbon generates glyceraldehyde 3-phosphate (G3P) which will be used to synthesize glucose. Therefore, the correct answer is e.
