Photosynthesis

The final electron acceptor in photosynthesis is NADP+ (nicotinamide adenine dinucleotide phosphate). NADP+ accepts electrons, along with hydrogen ions, from the electron transport chain in the thylakoid membrane, and is reduced to NADPH, which is a key molecule in the production of carbohydrates during the light-independent reactions of photosynthesis.

Photosynthesis (in green plants) uses sunlight as energy so it can make carbohydrates from carbon dioxide and water. Cellular respiration (usually animal cells) makes energy breaking down carbohydrates and produces carbon dioxide and water.

The source of energy for the process of photosynthesis is sunlight. Through a series of complex reactions, plants and other photosynthetic organisms convert light energy into chemical energy in the form of glucose. This process is essential for the production of oxygen and is at the foundation of the Earth's food chain.

Sunlight: the energy source that powers the process of photosynthesis.

If by "second stage" you mean the Calvin cycle, then you need 3 CO2 and 2 ATP and 1 NADPH.

Light intensity is a key environmental factor that can affect the rate of photosynthesis. As light intensity increases, so does the rate of photosynthesis, up to a certain point where it plateaus. Other factors such as temperature and carbon dioxide concentration can also influence photosynthesis rate.

Photosynthesis needs carbon dioxide, water, and sunlight to produce glucose. Carbon dioxide is taken in through the stomata on the leaves, water is absorbed by the roots and transported to the leaves, and sunlight is captured by chlorophyll in the chloroplasts to drive the process of photosynthesis.

chemical energy is stored energy

For example: tree stores energy that it had received from the sun (thermal and heat energy)

Your body uses aerobic respiration to produce energy for activities like running or biking. During aerobic respiration, cells use oxygen to break down glucose into ATP, the energy currency of the cell. This process occurs in the mitochondria of cells and provides the energy needed for muscle contractions and movement.

Ribosomes are not directly involved in carbohydrate synthesis. They are responsible for protein synthesis by translating mRNA into polypeptide chains. Carbohydrate synthesis occurs in the cytoplasm through various metabolic pathways.

No.

Chlorophyll, the molecule in plant cells that traps sunlight energy which is used to power the photosynthetic assembly of sugars, is green in colour.

Any molecule that appears green in colour when illuminated by white light (sunlight), is absorbing all the colours (spectrum) which make up white light EXCEPT the green part of the light spectrum, which it is reflected (so that the green light comes back to our eyes).

Thus as green light is being reflected away form the plants, the energy of green coloured light can not be used to promote photosynthesis.

During photosynthesis, no chemical reaction gives off heat. Photosynthesis is an endothermic process, meaning it requires energy in the form of sunlight to convert carbon dioxide and water into glucose and oxygen.

Carbon dioxide in the air is the source of carbon that plants use for photosynthesis. Through the process of photosynthesis, plants convert carbon dioxide, water, and sunlight into glucose and oxygen. Plants absorb carbon dioxide through tiny pores in their leaves called stomata.

A prokaryote that carries out photosynthesis is called a cyanobacterium. These organisms are capable of capturing sunlight and converting it into energy through the process of photosynthesis. Cyanobacteria are often found in aquatic environments and are important producers of oxygen in ecosystems.

The light-dependent reactions, or light reactions, are the first stage of photosynthesis. In this process light energy is converted into chemical energy, in the form of the energy-carriers ATP and NADPH. In the light-independent reactions, the formed NADPH and ATP drive the reduction of CO2 to more useful organic compounds, such as glucose.

In photosynthesis, the stroma is where the Calvin cycle takes place, which is the process responsible for fixing carbon dioxide and producing glucose. It is also where enzymes and other molecules necessary for the synthesis of sugars are located. The stroma acts as a site for various biochemical reactions that ultimately lead to the production of energy-rich molecules for the plant.

Chloroplasts are the organelles responsible for initiating photosynthesis in plant cells. They contain chlorophyll, a pigment that absorbs light energy and converts it into chemical energy through a series of reactions.

If water were no longer available for photosynthesis, the plant would not be able to produce glucose, which is essential for its growth and survival. This would lead to wilting, reduced turgor pressure, and ultimately, the death of the plant due to lack of energy and nutrients.

NADPH is the other molecule produced in the second stage of photosynthesis, known as the light-dependent reactions. Both ATP and NADPH are essential for the production of sugars in the Calvin cycle, which is the third stage of photosynthesis.

The equation for respiration is:

Glucose + Oxygen ---------> Carbon Dioxide + Water (+ Energy)

The equation for photosynthesis is:

Light

Carbon Dioxide + Water ----------------> Glucose + Oxygen

Energy

So basically photosynthesis is the opposite of respiration and vise versa! :) I hope this has helped

Photosynthesis requires light and carbon dioxide (CO2). Furthermore, the plant requires water and nutrients for other growth and other biochemical pathways. Water can be absorbed from the soil. Light and CO2 can be absorbed through the plants leaves.

The atmosphere was changed from being a reducing one to an oxidizing one. Then, the most important change was regarding the relative concentration of molecular oxygen, which is thought to have incremented a thousand times. Concomitantly the ozone layer also formed.

Photosynthesis converts light energy into chemical energy in the form of glucose. In this process, plants use sunlight to convert carbon dioxide and water into oxygen and glucose, which serves as a source of energy for the plant.

The end product of the light reaction of photosynthesis is ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules are used to fuel the Calvin cycle, the second stage of photosynthesis where carbon dioxide is converted into glucose.
