Why is photosynthesis a balanced equation?

Reactions must be balanced, meaning there needs to be same number each atom on the reactant side as there is on the products side. As you can see, there are 4 hydrogen atoms and 2 oxygen atoms on both sides of the equation. This makes the equation balanced.

How do you describe the process of photosynthesis?

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

What is the equation of photosynthesis for Class 7?

Answer: carbon dioxide + water —> glucose + oxygen + wate it can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2.

What is the formula for photosynthesis in words?

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

What is photosynthesis explain with diagram?

Through a process called photosynthesis, plants use energy in sunlight to turn a gas called carbon dioxide and water into sugar. Plants then use this sugar to grow. At the same time, plants produce a gas called oxygen as a waste product, which is lucky for us and other animals because we need oxygen to breathe!

What is photosynthesis very short answer?

Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.

What is photosynthesis long answer?

Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules.

What are two stages in photosynthesis?

There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.

What is Stage 1 of photosynthesis called?

Photosynthesis Stage I: The Light Reactions. The first stage of photosynthesis is called the light reactions. During this stage, light is absorbed and transformed to chemical energy in the bonds of NADPH and ATP.

What happens in Stage 1 of photosynthesis?

Stage one: light reactions Light energy absorbed by chlorophyll is converted into chemical energy. Some of this energy is used to split water into hydrogen and oxygen. Some of the chemical energy is used to make ATP from ADP and phosphate (Pi). This chemical energy is stored as ATP.

What is the difference between photosystems 1 and 2?

The two main multi-subunit membrane protein complexes differ in their absorbing wavelength, where the photosystem I or PS 1 absorbs the longer wavelength of light which is 700 nm while photosystem II or PS 2 absorbs the shorter wavelength of light 680 nm.

What is Z scheme?

The “Z‐scheme” describes the oxidation/reduction changes during the light reactions of photosynthesis. Absorption of a photon excites P680 to P680*, which “jumps” to a more actively reducing species. P680* donates its electron to the quinone‐cytochrome bf chain, with proton pumping.

What are the two types of photosystems?

3.3. Physically, photosystems are found in the thylakoid membranes. There are two kinds of photosystems: photosystem I (PSI) and photosystem II (PSII) (Fig. 3.3).

What colors does photosystem 2 absorb?

The Colors of Photosynthesis These light-absorbing molecules include green chlorophylls, which are composed of a flat organic molecule surrounding a magnesium ion, and orange carotenoids, which have a long string of carbon-carbon double bonds. These molecules absorb light and use it to energize electrons.

Is oxygen used in photosystem 1?

Photosystem II obtains replacement electrons from water molecules, resulting in their split into hydrogen ions (H+) and oxygen atoms. The oxygen atoms combine to form molecular oxygen (O2), which is released into the atmosphere. Photosystem I obtains replacement electrons from the electron transport chain.

What is the final product of photosystem 2?

Cards

What is the function of photosystem I?

Photosystem I, a membrane protein complex found in all oxygenic photosynthetic organisms, uses light energy to transfer electrons from plastocyanin to ferredoxin. Light energy captured by antenna chlorophylls is transferred rapidly to the primary electron donor, P700.

What is a photosystem composed of?

A photosystem is composed of a protein complex called a reaction center complex surrounded by several light-harvesting complexes.

What is produced in photosystem 2?

Photosystem is the form of pigments on the thylakoid membrane1. Photosystem II is the first membrane protein complex in oxygenic photosynthetic organisms in nature. It produces atmospheric oxygen to catalyze the photo-oxidation of water by using light energy.

What is the main role of photosystem 2?

Photosystem II (PSII) is a multi-component pigment-protein complex that is responsible for water splitting, oxygen evolution, and plastoquinone reduction.

What are the functions of photosystem I and photosystem II in plants?

Photosystem II produces a proton gradient that drives the synthesis of ATP. Photosystem I yields reducing power in the form of NADPH. Although several groups of bacteria have just one of the two photosystems, the cyanobacteria, algae, and plants have both.

Where is ps2 located?

Photosystem II (or water-plastoquinone oxidoreductase) is the first protein complex in the light-dependent reactions of oxygenic photosynthesis. It is located in the thylakoid membrane of plants, algae, and cyanobacteria.

What event occurs in photosystem II?

Photosystem II obtains replacement electrons from water molecules, resulting in their split into hydrogen ions (H+) and oxygen atoms. The oxygen atoms combine to form molecular oxygen (O2), which is released into the atmosphere. The hydrogen ions are released into the lumen.

What event occurs in photosystem?

The event that happens in photosystem I is that electrons are transferred to ferredoxin. This is a part of photosynthetic light reactions which makes use of light energy to transfer electrons from plastocyanin to ferredoxin.

What event occurs in photosynthesis?

Answer Expert Verified The three events that occur during the process of photosynthesis are: (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen. (iii) Reduction of carbon dioxide to carbohydrates.

Does photosystem 2 produce ATP?

Electrons are transferred sequentially between the two photosystems, with photosystem I acting to generate NADPH and photosystem II acting to generate ATP. Electron transport through photosystem II is thus coupled to establishment of a proton gradient, which drives the chemiosmotic synthesis of ATP.

How is ADP converted to ATP?

ADP is combined with a phosphate to form ATP in the reaction ADP+Pi+free energy→ATP+H2O. The energy released from the hydrolysis of ATP into ADP is used to perform cellular work, usually by coupling the exergonic reaction of ATP hydrolysis with endergonic reactions.

What stimulates ATP synthesis?

During electron transport, the participating protein complexes push protons from the matrix out to the intermembrane space. This creates a concentration gradient of protons that another protein complex, called ATP synthase, uses to power synthesis of the energy carrier molecule ATP (Figure 2).

What is the role of ATP synthase in photosynthesis?

In the electron transport chain of photosynthesis, the ATP synthase complex accomplishes the phosphorylation of ADP to ATP, providing part of the energy for subsequent biosynthesis through the Calvin cycle. …

How much co2 is produced in glycolysis?

six CO
