Question: Does Photosynthesis Produce ATP?

Is ATP produced during photosynthesis?

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 much ATP is produced in photosynthesis?

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 gas is used in photosynthesis?

carbon dioxideTo perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.

Which gas is used by plants?

Answer and Explanation: Plants use carbon dioxide, oxygen and water in photosynthesis.

Which gas is released by plants?

Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

What are 3 ways we use ATP?

ATP (Adenosine Triphosphate)Energy Currency. The cells energy yielding reactions synthesise ATP, and ATP is used by the cell in all forms of work. … Synthesis. … Active Transport. … Muscle Contraction.

What process uses ATP?

Almost all cellular processes need ATP to give a reaction its required energy. ATP can transfer energy and phosphorylate (add a phosphate) to other molecules in cellular processes such as DNA replication, active transport, synthetic pathways and muscle contraction.

How do plants produce ATP?

During photosynthesis a plant takes in water, carbon dioxide and light energy, and gives out glucose and oxygen. It takes light from the sun, carbon and oxygen atoms from the air and hydrogen from water to make energy molecules called ATP, which then build glucose molecules.

Do plants take in oxygen?

Plants release oxygen during the day in the presence of natural light through the process of photosynthesis. While at night, the plants uptake oxygen and release carbon dioxide, which is called respiration.

How much oxygen is released during photosynthesis?

It takes six molecules of CO2 to produce one molecule of glucose by photosynthesis, and six molecules of oxygen are released as a by-product.

Which light is most effective in photosynthesis?

The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.

Does photosynthesis produce ATP or glucose?

The stages of photosynthesisStageLocationEventsLight-dependent reactionsThylakoid membraneLight energy is captured by chloroplasts and stored as ATPCalvin cycleStromaATP is used to create sugars that the plant will use to grow and live

Where is co2 used in photosynthesis?

Plants extract the carbon dioxide from the air and use it in photosynthesis process to feed themselves. The carbon dioxide enters the leaves of the plant through small pores called stomata. Once the carbon dioxide enters the plant, the process begins with the help of sunlight and water.

Does photosynthesis require oxygen?

By using the energy of sunlight, plants can convert carbon dioxide and water into carbohydrates and oxygen in a process called photosynthesis. As photosynthesis requires sunlight, this process only happens during the day. … Oxygen is required to do this.

Where ATP is produced during photosynthesis?

thylakoid membraneATP is produced on the stromal side of the thylakoid membrane, so it is released into the stroma. The electron arrives at photosystem I and joins the P700 special pair of chlorophylls in the reaction center.

Why is red light best for photosynthesis?

The primary reasons why LED fixtures emit a lot of red are 1) red LEDs are among the most efficient at converting electricity into photosynthetic photons, 2) chlorophyll strongly absorbs red light, thus it is effective at photosynthesis, and 3) red LEDs are relatively inexpensive.

Does photosynthesis produce energy?

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Do plants use ATP?

Eukaryotic Cell Structure and Function Most cells use ATP as their main form of energy. Most eukaryotic cells, including plant cells, get their ATP from the process of cellular respiration. Cellular respiration takes place in the mitochondria. … Plants need to do something with all that glucose they make!

What produces the most ATP?

The Krebs cycle takes place inside the mitochondria. 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). The electron transport chain takes place in the mitochondria.

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 the role of ATP in photosynthesis?

Photosynthesis occurs in two stages- light reaction and dark reaction. During the light reaction reduced NADPH2 and ATP are synthesized. These products are used subsequently to reduce carbon dioxide into sugars. Thus, the purpose of ATP in photosynthesis is to transfer energy from light reaction to dark reaction.
