Photosynthesis

This category is for questions about the chemical process in which autotrophic organisms use sunlight, carbon dioxide and water to make glucose, water and oxygen. This process is vital to life and is of great importance in biology.

What is the link between respiration and photosynthesis?

the carbon dioxide emitted during respiration is used in photosynthesis

Does photosynthesis use carbon dioxide and water as a reactant?

Yes,the reactants are CO2 and H2O.End products are Glucose and Oxygen.

What two colors of light drive most photosynthesis?

The two colors of light that drive most photosynthesis are red and blue light. These wavelengths are absorbed most effectively by chlorophyll, which is the pigment responsible for capturing light energy during photosynthesis.

What are 3 materials required for photosynthesis?

The 3 materials needed for photosynthesis are water, carbon dioxide, and sunlight. These 3 materials combined enable the plant to make a sugary substance known as glucose. 6 molecules of water+6 molecules of carbon dioxide=1 molecule of sugar+6 molecules of oxygen* *=The plant doesn't need the oxygen so it releases it into the air. That's how we get our oxygen. :)

What is light-depent reaction in photosynthesis?

It means that for a reaction (usually chemical) to take place, light is needed. An example of this can be seen in photosynthesis.

What is the role of RuBp in Calvin cycle?

It is an enzyme that triggers the carboxylation (combining of carbon dioxide) of ribulose biphosphate in the stroma of chloroplasts in plants. This carboxylation is the first step of the light-dependant reaction that occurs in plants and this light-dependant reaction is the second stage of photosynthesis.

What molecule is the source of basic material used for the production of glucose in the Calvin or light independent cycle of photosynthesis?

Mainly the molecules used in the Calvin Cycle are from the light reactions prior to it, and therefore, the ATP energy made in the light reaction fuels the Dark Reaction which will eventually form Glucose

Do plants use the oxygen released during photosynthesis for respiration?

Yes, plants, just like animals, require oxygen for the process of respiration. But during the day hours, they are involved in photosynthesis which requires the intake of carbon dioxide. The rate of respiration in plants is very low as compared to the rate of photosynthesis.

How glucose manufactured during the process of photosynthesis?

The glucose produced by photosynthesis isn't stored; it is sent down the phloem to the roots and the other parts of the plant to be transformed into ATP (energy), which is used by the plant to perform various life functions (one of the most important being growth).

What is the main product of carbon dioxide?

The main product of carbon dioxide is oxygen. During the process of photosynthesis, plants take in carbon dioxide and water, and in the presence of sunlight, they produce oxygen as a byproduct. This oxygen is released into the atmosphere, which is essential for sustaining life on Earth.

Where are granum and thylakoids found?

Grana are stacks of thylakoids.They are in stroma.

Where do plants get the carbon they use to make organic molecules?

Plants get the carbon they use to make organic molecules from carbon dioxide in the air through the process of photosynthesis. During photosynthesis, plants use sunlight to convert carbon dioxide into glucose and other organic compounds, which they use as building blocks for growth and energy.

Is granum or stroma a part of photosynthesis?

A multi-layered membrane unit formed by stacks of the lobes of branches of chloroplast thylakoid

How are photosynthesis transpiration and respiration related?

both are processes that provide energy for cells/organisms. photosynthesis provides energy for photoautotrophs through light reactions in the thylakoids and the Calvin cycle. ellular respiration gives hetertrophs the energy they need through glycolysis, the Krebs cycle, and electron transport system

What would happen to the rate of photosynthesis if the concentration of carbon dioxide decreased?

Rate is often proportional to the concentration of the reactants. If the carbon dioxide were less concentrated we should expect the rate to decrease, other factors being equal.

Is photosynthesis the most important chemical reaction for life on earth?

grade 9 academic science ?? ;)

anyhow...

photosythesis should win the most important chemical reaction on earth "award" because if there was no photosynthesis, it would mean the end of plants generating oxygen. So therefore all living things would die because no living things can survive without oxygen!
