Which of these phosphorylates ADP to ATP?

Terms in this set (10) ATP synthase phosphorylates ADP.

When and how is oxygen released as a by product in the photosynthesis?

All photosynthetic eukaryotic cells contain chloroplasts that use the radiant energy of sunlight to convert carbon dioxide and water into carbohydrates. As a byproduct of photosynthesis, oxygen gas is also released into the atmosphere through tiny openings in the leaves called stomata.

Is oxygen produced during photosynthesis?

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Is oxygen a reactant or product?

They indicate the number of each chemical species that reacts or is formed. Methane and oxygen (oxygen is a diatomic — two-atom — element) are the reactants, while carbon dioxide and water are the products.

Which is the source of oxygen for the product and byproduct of photosynthesis?

water The oxygen released during photosynthesis is from the water. The plants will absorb water as well as carbon dioxide during photosynthesis. Later these water molecules are converted into oxygen and sugar.

Which of the following materials are direct products of photosynthesis?

In photosynthesis, energy from light is used to convert carbon dioxide and water into glucose and oxygen. For 6 carbon dioxide and 6 water molecules, 1 glucose molecule and 6 oxygen molecules are produced.

What molecule is split in the oxygen releasing light reactions of photosynthesis?

In the light-requiring reactions of photosynthesis water molecules (H2O) are split apart by light energy (captured by photosynthetic pigments). Oxygen atoms released from the splitting of water molecules combine in pairs, forming O2 molecules, and these diffuse out of the leaf through the stomates.

Why can C4 plants photosynthesize without?

Why are C4 plants able to photosynthesize with no apparent photorespiration? They use PEP carboxylase to initially fix CO2. fix CO2 into organic acids during the night. The alternative pathways of photosynthesis using the C4 or CAM systems are said to be compromises.

Which of the following events occurs in the light reactions of photosynthesis?

The events occurring in the light reaction of the photosynthesis are: Absorption of sunlight by the chlorophyll and release of the electron to the carriers. Photolysis of water to provide the electron to the chlorophyll. The release of molecular oxygen due to the photolysis of water.

What phosphorylates ADP?

“There are a few that phosphorylate ADP into ATP, but one of the more significant ones is the enzyme called (creatively enough) ATP Synthase, which is located in the Electron Transport Chains of both the inner mitochondrial membrane for cellular respiration and in the thylakoid (I think?)

What is the direct mechanism of ATP production 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.

Which of the following is a product of the light reactions of photosynthesis group of answer choices?

The basic function of the light reactions of photosynthesis is the production of glucose. The basic function of the light reactions of photosynthesis is the conversion of solar energy to chemical energy.

During what stage of photosynthesis is o2 released?

Light Reactions The Light Reactions

How is oxygen produced?

The most common natural method is photo-synthesis, in which plants use sunlight convert carbon dioxide in the air into oxygen. … Oxygen can also be produced as the result of a chemical reaction in which oxygen is freed from a chemical compound and becomes a gas.

How much oxygen is produced in 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. A glucose molecule contains six carbon atoms, so that’s a net gain of one molecule of oxygen for every atom of carbon added to the tree.

How is oxygen a reactant?

Both hydrogen and oxygen gases exist as diatomic (“two-atom”) molecules. These molecules are the reactants in the reaction.

What happens to the products of photosynthesis?

Let’s look at the products of photosynthesis! During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O₂) and a form of sugar called glucose (C₆H₁₂O₆). … The oxygen will leave the plant through the stomata and enter Earth’s atmosphere.

What is product and reactant?

The substance(s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction. … A product is a substance that is present at the end of a chemical reaction.

What is the source of oxygen released from plants during day?

photosynthesis 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.

What is the source of oxygen evolution and oxygen in glucose with respect to photosynthesis?

In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct. The glucose molecules provide organisms with two crucial resources: energy and fixed—organic—carbon.

What are the 4 products of photosynthesis?

The reactants for photosynthesis are light energy, water, carbon dioxide and chlorophyll, while the products are glucose (sugar), oxygen and water.

When oxygen splits into hydrogen and oxygen during the light reaction phase?

photolysis That replacement process also requires light, working with an enzyme complex to split water molecules. In this process of photolysis (“splitting by light”), H₂O molecules are broken into hydrogen ions, electrons, and oxygen atoms. The electrons replace those originally lost from chlorophyll.

What molecule is split apart during the light reactions?

water molecule During Light reactions of Photosynthesis, the chlorophyll will be activated by light. This light activated chlorophyll will split the water molecule. This process is called Photolysis. Water molecule is split to release H+ ions and also oxygen.

What happens to oxygen produced by the light dependent reactions?

In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen as a byproduct as water is broken apart.

Which of the following reactions produce oxygen in plants?

The light-dependent reactions of photosynthesis use water and produce oxygen.

Why do C4 plants photosynthesis?

In C4 photosynthesis, where a four-carbon compound is produced, unique leaf anatomy allows carbon dioxide to concentrate in ‘bundle sheath’ cells around Rubisco. … What’s more, this adaptation allows plants to retain water through the ability to continue fixing carbon while stomata are closed.

Are most plants C3 or C4?

C3 and C4 photosynthesis. The majority of plants and crop plants are C3 plants, referring to the fact that the first carbon compound produced during photosynthesis contains three carbon atoms. Under high temperature and light, however, oxygen has a high affinity for the photosynthetic enzyme Rubisco.

How is oxygen produced in light reaction?

During the light reaction in photosynthesis, oxygen is released as by product by absorbing light energy by chlorophylls. Source of this oxygen is water. Water splits into hydrogen and hydroxyl ions. The hydroxyl ions released oxygen.
