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 2 things are created during photosynthesis?

Oxygen and glucose are the two main products created during photosynthesis. Oxygen is released as a byproduct, while glucose is a sugar molecule used as an energy source for the plant.

What is released in light reactions of photosynthesis and which of these products does not participate in the dark reactions?

In the light reactions of photosynthesis, oxygen is released as a byproduct. Oxygen is not directly involved in the dark reactions (Calvin cycle), which utilize ATP and NADPH produced during the light reactions to convert carbon dioxide into sugars.

The energy plants use during photosynthesis comes from what?

Plants harness energy for photosynthesis from sunlight, which is absorbed by chlorophyll molecules in their cells. This absorbed sunlight drives the process that converts carbon dioxide and water into glucose and oxygen.

Where does photosynthesis mainly take place?

Photosynthesis takes place in the chloroplasts of a plant cell. Chloroplasts possess chlorophyll, which allow them to absorb energy from sunlight and other elements to start the process of photosynthesis.

Where in chloroplasts is light energy absorbed?

chloroplast have membrane bound sac like structures piled up on top of each other called thylakoids which have chlorophyll(pigment having "Mg"ion) filled in them, this pigment is primarily responsible for absorption of photons of light

Energy transfer involved in photosynthesis?

A theoretical model is presented to account for the physical mechanism of energy transfer from antenna molecules to the reaction centers in photosynthesis. The energy transfer is described by a generalized transport equation or "master equation". The solution of this equation for the proposed model gives a relationship between the antennae interaction energy and the transfer rate. The results are shown to be in agreement with inter-antenna transfer rates calculated from experimental fluorescence lifetimes. Previous theories were based either on the Förster mechanism, which is valid for very small interaction energies, or an exciton model valid for very large interactions, but experimental results seemed to indicate that the actual situation was intermediate between these two. The Förster theory and the exciton model are limiting cases of the master equation.

In photosynthesis energy combines with carbon dioxide and water to form?

Photosynthesis is a very complex process performed by plants.

Overall, carbon dioxide, oxygen, and the presence of light allows plants to form glucose (or other organic compounds) and release oxygen.

Where do ventriloquist perform?

Ventriloquists typically perform in a variety of venues such as comedy clubs, theaters, cafes, schools, and even on television. They may also be hired for private events like parties, corporate functions, and cruise ships. Their performances can range from family-friendly entertainment to more adult-oriented shows.

What is the main goal of photosynthesis?

The main goal of photosynthesis is to convert sunlight into chemical energy in the form of glucose (sugar) that the plant can use as food for growth and development. This process also produces oxygen as a byproduct, which is released into the atmosphere.

What type of reaction is involved in many of the chemical reactions of photosynthesis?

Many of the chemical reactions in photosynthesis are redox reactions, involving both reduction and oxidation processes. In photosynthesis, carbon dioxide is reduced to sugars, while water is oxidized to produce oxygen.

What does chlorophyl do?

It traps sunlight energy for the plant and then helps begin the process of photosynthesis. It absorbs the red and blue color from the light and reflects the green so that's why we see green leaves when chlorophyll is present. The chorophyll also helps the light dependent reactions in the thylakoids produce ATP and NADPH. These are later used in the Calvin Cycle to produce glucose.
Chlorophyll is the liquid substance in a plant cell that gives it its color.

Plants make food when sunlight strikes chlorophyll.
Chlorophyll is a green pigment that is found in the chloroplast of the leaf. It help to traps light energy for photosynthesis...
Chlorophyll helps plants to make energy from sunlight, carbon dioxide, and water.

Photosynthesis relies on gas defusion briefly describe the process of gas diffusion and explain what is meant by concerntration gradient?

well concentration gradient is when both sides are evened out and if both sides are evened out then they are withconcentration gradient but when they are not evened they are against concentration gradient!

What is the principal end product of photosynthesis?

The principal end product of photosynthesis is glucose, a simple sugar molecule that serves as the main energy source for plants.

Does photosynthesis produce heat?

Yes, photosynthesis does not produce heat as its primary purpose is to convert sunlight into chemical energy in the form of glucose. Heat is a byproduct of metabolic processes that occur during cellular respiration, which uses glucose to produce energy for the plant.

What do plants receive from animals in photosynthesis?

plants receive carbon dioxide from animals whichh is something they need to make oxygen for us

What is photosynthesis include chlorophyll?

Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities. The process begins with energy from light being absorbed by proteins called reaction centers that contain green chlorophyll pigments.

What is the main result of the reactions of the Calvin cycle?

The main result of the reactions in the Calvin cycle is the conversion of carbon dioxide into glucose, which is a form of stored energy. This process requires ATP and NADPH produced during the light-dependent reactions of photosynthesis.

What cell does chemiosmosis take place in?

Chemiosmosis occurs with those protons diffuse back, out of the intermembrane space, across the inner mitochondrial membrane, back into the matrix: as they do so, they pass through the membrane spannning ATP synthases which make ATP from ADP + Pi.

Is dew a result of transpiration or photosynthesis?

Dew is primarily a result of condensation of water vapor in the atmosphere onto cool surfaces, such as grass or leaves. Transpiration is the process by which plants release water vapor through their leaves, while photosynthesis is the process by which plants convert light energy into chemical energy. Dew formation is not directly related to either of these processes, although plants can contribute to dew formation by providing a surface for water vapor to condense on.

Does plankton make it own food?

No, plankton do not make their own food through photosynthesis like plants do. Plankton are either phytoplankton, which are plant-like and produce their own food through photosynthesis, or zooplankton, which are animal-like and must consume other organisms for food.

What is the function of vascular system?

The vascular system functions by transporting nutrients, oxygen, hormones, and waste products throughout the body. It consists of blood vessels (arteries, veins, and capillaries) that carry blood to and from different parts of the body. The vascular system also helps regulate body temperature and plays a crucial role in immune response.

What happen to the water molecules when the plants absorbs light energy during photosynthesis?

The water molecules split into hydrogen ions, electrons and oxygen atoms. The oxygen atoms join together to form oxygen molecules = oxygen gas which is released from the plant into the air. The hydrogen ions get taken up by a carrier molecule called NADP. The electrons become energised using the light energy that has been trapped by the chlorophyll and eventually join the hydrogen ions attached to the NADP. Ultimately the hydrogen ions and energised electrons join with carbon dioxide to form simple sugars = carbohydrate, from which ALL other organic compounds in the plant are made.
