Photosynthesis

The equation for photosynthesis is:

Carbon dioxide + water + light --> glucose + water + oxygen

Therefore, photosynthesis produces glucose (stored in plant as sugar), water (lost through transpiration and kept for the plant), and oxygen (released into air).

Glucose and other sugars (all made during photosynthesis) are the fuels that power all living things. Since water is used as the electron donor in oxygenic photosynthesis, it become part of the sugar molecules.........................................................

A chloroplast is a double membrane organelle that captures light energy and converts it to chemical energy through photosynthesis. It contains chlorophyll, a pigment that absorbs light energy, and carries out the complex series of reactions that convert carbon dioxide and water into sugars.

The two main inputs for photosynthesis are sunlight and carbon dioxide. Plants use these inputs to produce glucose (energy) and oxygen as byproduct.

The chloroplasts, specifically found within the cells of the mesophyll tissue, contain the chemicals needed for photosynthesis to occur in a leaf. These chemicals include chlorophyll, which is responsible for capturing light energy, and other molecules essential for the series of reactions involved in photosynthesis.

Water is essential for the light reaction in photosynthesis because it is the source of electrons needed to replace the ones lost from chlorophyll during the light-capturing process. When light energy is absorbed by chlorophyll, it triggers the splitting of water molecules into oxygen, protons, and electrons. These electrons are then used to replenish the ones lost by chlorophyll, allowing the process of photosynthesis to continue.

Drosera, a type of carnivorous plant, traps insects to supplement its nutrient intake, especially in environments with poor soil conditions. While it can photosynthesize to produce sugars, it relies on the nutrients obtained from the trapped insects, such as nitrogen and phosphorus, to support growth and reproduction. This dual strategy allows Drosera to thrive in nutrient-deficient habitats.

The close proximity of photosystems I and II in the thylakoid membrane allows for efficient transfer of electrons between the two complexes. This facilitates the rapid movement of electrons during the light reactions of photosynthesis, maximizing the production of ATP and NADPH.

Photosynthesis is not a bodily function of animals (humans included), but it is important for our survival. Plants go through photosynthesis to create food and nutrients for their survival. It happens that one of the waste products of this cycle is oxygen, which we breathe in.

Cellular respiration, on the other hand, occurs in both plants and animals. It is an important function that creates energy.

Yes, carbon dioxide is the only product of the Krebs cycle that is not reused or used in other stages of cellular respiration. The other products of the Krebs cycle, such as ATP, NADH, and FADH2, are all used in the electron transport chain to produce more ATP.

Using Carbon from CO2, energy from ATP, and high-energy electrons from NADPH, the Calvin Cycle constructs an energy-rich sugar molecule called glyceraldehyde 3 phosphate (G3P). The plant cell can then use G3P as the raw material to make the glucose and other organic compounds that it needs. This occurs within the stroma of a chloroplast.

The reduction of CO2 occurs in photosynthesis, where plants convert CO2 into carbohydrates using sunlight. In respiration, organisms use carbohydrates as a fuel source and release CO2 back into the atmosphere.

Plants primarily use red and blue wavelengths for photosynthesis, as these are most effective for driving the process. This leaves behind green wavelengths, which are reflected back to our eyes and is why most leaves appear green to us.

The chloroplast is the organelle where photosynthesis occurs, though it is not found in all plant cells (only those on the surface). For example, tubas (e.g. potatoes) and roots do not contain chloroplasts as they have no exposure to sunlight.

During transpiration, water vapor is released from plant leaves into the atmosphere, which exchanges gases such as carbon dioxide (CO2) and oxygen (O2) with the surrounding air. This process helps regulate the plant's internal water balance and aids in photosynthesis.

Did you mean Photysystem I and Photosystem II. They both are overall identical except that Photosystem I is actually a later part of the process of Photosynthesis than Photosystem II, its only called Photosystem I because it was discovered first. Photosynthesis starts when light excites Photosystem II causing it to break up H20 that comes from the roots into H2 and 02. (If you are wondering why oxygen becomes two molecules when in H20 there is only one molecule of it, that is because it cannot exist as one molecule stably therefore it bonds with another oxygen from another break down almost instantly.) Then Photosystem II sends electrons across the electron transport pathway (along the membrane of the Thylakoid in between the two photosystems) to Photosystem I which then uses them to convert NaDP+ into NaDPH by adding a phosphate group from outside the Thylakoid. Thats pretty much what each Photosystem does and both are located inside the Thylakoid membrane.

Plants with non-green leaves like variegated plants still have chlorophyll, but in lower amounts compared to green plants. They can still carry out photosynthesis, although at a slower rate. Variegation is caused by the presence of other pigments in the leaves, which can sometimes mask the green color from chlorophyll.

Even i wanted to know the answer to this question!! :p

6CO2+12H2O---> C6H12O6 + 6H2O + 6O2

I feel the number 12 preceding H2O in the equation of photosynthesis is merely the stoichiometric coefficient that is necessary to show that since 24 atoms of hydrogen are produced, hence 24 hydrogen atoms ought to be used....:/...

Factors such as high temperatures, excessive light intensity, and pollution can lead to a rapid decline in photosynthesis rate if they rise above a certain level. These conditions can damage the photosynthetic machinery within plants, disrupting the process of photosynthesis and reducing its efficiency.

Two phases are at equilibrium when the rate of their interconversion is equal in both directions. This means that the amount of substance transitioning from one phase to another is the same in both directions, resulting in a stable balance between the phases.

For photosynthesis, plants need water, carbon dioxide, and sunlight (or photons).

The water provides electrons, the sunlight provides the energy, and CO2 provides a carbon source.

The oxygen atoms in the oxygen gas produced by photosynthesis come from water molecules that are split during the light-dependent reactions. The oxygen molecules released are a byproduct of this process.

1. In a controlled photosynthesis pond algae can be used to break down organic wastes.

2. Cultivating algae to produce biofuel.

3. Carbon dioxide mitigation through controlled photosynthesis.

4. Surgery for the treatment of gas gangrene is performed under conditions of hyperbaric oxygen because the organisms causing it are anaerobic. Antibiotics and oxygen combine to kill them more effectively than antibiotics alone because they live only in the absence of oxygen.

5. Polymixins are antibiotics that work by inhibiting bacterial respiration.

6. Other classes of drugs work by uncoupling oxidative phosphorylation in aerobic bacteria.

High-energy electrons generated during the light reactions of photosynthesis are used to create a proton gradient across the thylakoid membrane. This gradient drives the production of ATP, providing the energy needed for the light-independent reactions. Additionally, the high-energy electrons are used to reduce NADP+ to NADPH, which is essential for the synthesis of sugars during photosynthesis.
