Photosynthesis

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.

light independent reaction

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.

The reactants of photosynthesis are carbon dioxide, water, and light energy. Carbon dioxide is absorbed from the air, water is taken up through the roots, and light energy is captured by chlorophyll in plant cells to drive the process of photosynthesis.

Root hair cells are found underground, where there is no light. Chloroplasts help the process of photosynthesis. As there is no light, no photosynthesis takes place so chloroplasts are not needed.

there are many things that affect photosynthesis the main 2 are carbon dioxide levels and light. pottaisium hydrogencarbonate is sometimes added to the water because it provides carbon dioxide this is needed for photosynthesis. Light intesity is the biggest factor the more light intensity the more oxygen the plant produces

Photosynthesis produces starch which is stored as glucose, if the plant cannot photosynthesis for any reason it turns to its glucose/ starch storage and uses it in the plant.

Photosynthesis is a crucial process for plants as it allows them to convert sunlight into energy, in the form of glucose. This energy is essential for the plant to grow, develop, and carry out its daily functions. Photosynthesis also releases oxygen as a byproduct, which is vital for sustaining life on Earth.

Water is split in the light reactions of photosynthesis to provide electrons for the photosynthetic electron transport chain. This process releases oxygen as a byproduct. Additionally, water molecules help maintain the balance of protons and electrons within the thylakoid membrane during the light reactions.

It takes place in the stoma

The concentration gradient of protons is potential energy and is harnessed by an enzyme called ATP synthase. ATP synthase converts the potential energy of the proton concentration gradient into chemical energy stored in ATP (the process is called chemiosmosis).

So without the protons, no ATP would be made, and therefore no light reaction would occur.
