The process of using the products of an exergonic reaction to carry out an endergonic reaction is called?

The process of using the products of an exergonic reaction to drive an endergonic reaction is known as energy coupling. This enables coupling the release of energy from one reaction to power a reaction that requires energy input. ATP is often involved in facilitating this energy transfer.

Is photosynthesis biochemistry?

Yes, photosynthesis is a biochemical process that occurs in plants, algae, and some bacteria. It involves capturing light energy and converting it into chemical energy in the form of glucose, using carbon dioxide and water.

The leaf surface area is just as if not more important than the intensity of light in photosynthesis?

The leaf surface area is indeed crucial for photosynthesis because it provides a larger area for light absorption and gas exchange. While light intensity is also important, having a sufficient leaf surface area allows for more efficient utilization of available light for photosynthesis. Ultimately, both factors must work together to maximize the process of photosynthesis.

What monitor the rate of photosynthesis in a plant?

The rate of photosynthesis in a plant can be monitored using a variety of methods, including measuring the production of oxygen, tracking changes in carbon dioxide levels, or using instruments like a spectrophotometer to measure the absorption of light by chlorophyll. These methods help scientists understand how environmental factors, such as light intensity and temperature, can impact the photosynthetic process in plants.

The use of light energy to convert water and carbon dioxide into energy-rich glucose molecules are called what?

The process you are referring to is called photosynthesis. In photosynthesis, plants use light energy to convert water and carbon dioxide into glucose and oxygen. This process is essential for the survival of plants and provides the foundation for most ecosystems on Earth.

How can you Describe the energy change in photosynthesis?

A plants leaf soaks up energy from the sun and converts it to sugar which it then uses as food/fuel and then it has energy to live and not die... then it releases its waste through its roots and pores. Plants also suck nutrients from the gound with their roots like nitrogen and such. That is used in the makeing of energy as well... the best answer you will get is in a science text book... go to the library cause even though i didn't i could have easily given you a bull crap answer so the library is key.

In the process of photosynthesis chlorophyll serves as?

In the process of photosynthesis, chlorophyll serves as the pigment that captures light energy from the sun. This light energy is then used to convert carbon dioxide and water into glucose and oxygen through a series of chemical reactions.

Plants that produce oxaloacetic acid instead of PGA during the dark reactions of photosynthesis are called?

Plants that produce oxaloacetic acid instead of PGA during the dark reactions of photosynthesis are known as C4 plants. These plants have adapted to hot and dry conditions by incorporating a four-carbon compound in the initial steps of carbon fixation to increase efficiency.

What happens to the water in a plant in photosynthesis?

The water combines with carbon dioxide and energy from the sun (photons) and creates carbohydrates (food for the plant) and free oxygen. So what "happens" to it is that the hydrogen and oxygen atoms get separated.

Why do water lilies not grow well in moving water?

Well, this is just a guess, but their roots are implanted into the ground while their flowers are floating on the water surface. Their stem has to stretch from the ground to the flower. So if the water moves, their stem may snap or their roots may be detached from the ground ( a bit too serious, maybe? ) Anyway, I'm not very sure. Maybe you can try wikipedia?

Hope I helped, at the very least! :)

How is an ADP molecule different from an ATP molecule?

Adenosine diphosphate or (ADP) is a compound that looks almost like ATP, except that it has two phosphate groups instead of three. This difference is the key to the way in which living things store energy. When a cell has energy available, it can store small amounts of it by adding a phospate group to ADP molecules, producing ATP.

What four things are nessessary in photosynthesis?

The four necessary things in photosynthesis are sunlight, water, carbon dioxide, and chlorophyll. Sunlight provides the energy needed for the process, water is used in the light-dependent reactions, carbon dioxide is absorbed from the atmosphere, and chlorophyll is the pigment that captures light energy.

Which by-product of photosynthesis was important in altering the atmosphere of the earth so that aerobic organisms could evolve?

short answer: oxygen

long answer:

Photosynthesis is the process where plants (or algae) produce carbohydrates (like glucose) and oxygen from carbon dioxide and water, using the energy of the sunlight. The increased oxygen concentration in the air made it possible for other organism to do aerobic respiration for their energy production. Aerobic respiration is the brakedown of sugars to carbon dioxide and water using oxygen, yielding energy for the cell.

photosynthesis: 6 CO2 + 6 H2O + light → glucose + 6O2

aerobic respiration: glucose + 6O2 → 6 CO2 + 6 H2O + energy

Does a rabbit carry out photosynthesis?

No, rabbits do not carry out photosynthesis. Photosynthesis is a process that occurs in plants, algae, and certain bacteria, where they convert sunlight into energy. Rabbits are animals that obtain energy by consuming plants and other organic matter.

Why bacteria cells cannot carry out ATP synthesis or photosynthesis?

Actually some can. There are some photosynthetic bacterias that can make food from sunlight. As for ATP synthesis, every cell is capable of making energy via glycolysis or photosynthesis (both producing minuscule amount, but nonetheless ATP).

Are sapwood and xylem the same?

No, sapwood and xylem are not the same. Sapwood is the outermost layer of wood in a tree that transports water and nutrients, while xylem is a type of vascular tissue within the tree that transports water and nutrients from the roots to the rest of the plant. Sapwood is composed of xylem cells, but xylem also includes other types of cells such as vessels and fibers.

What occurs if oxygen is absent during the second stage of cellular respiration?

If oxygen is not available during the second stage: the glucose (now pyruvate molecule, after glycolysis) the pyruvate can not enter the mitochondrial membrane so it takes an alternative method of producing ATP

Other organisms can continue 'cellular respiration' with out the need of O2 (anaerobic method) such as:

•Yeast

i) Alcohol fermentation

•Human Muscle cells

i) Produces lactic acid, which makes your muscles sore

How many ATP are produced from Calvin cycle?

The Calvin cycle does not directly produce ATP. However, ATP is required as an energy source for the Calvin cycle to function. ATP is typically generated through the light-dependent reactions of photosynthesis.

What does light carbon dioxide and water make?

Light, carbon dioxide, and water are the essential components needed for photosynthesis, a process by which plants and other organisms produce oxygen and glucose (sugar) as a result. Light energy is absorbed by chlorophyll in plants, which converts carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) and oxygen (O2).

What is a change in the way a plant grows in response to sunlight?

Phototropism is the change in the way a plant grows in response to sunlight. This process involves the plant bending towards the light source to optimize its exposure to sunlight for photosynthesis.

What explains the sequence of energy transformations during photosynthesis?

During photosynthesis, light energy is absorbed by chlorophyll in the chloroplasts and converted into chemical energy in the form of ATP and NADPH through the light-dependent reactions. This chemical energy is then used in the light-independent reactions (Calvin cycle) to convert carbon dioxide and water into glucose, a high-energy molecule that can be used by the plant for growth and metabolism.

State five essential conditions needed for photosynthesis to take place?

The five essential conditions needed for photosynthesis to take place are sunlight, carbon dioxide, water, chlorophyll, and enzymes. Without any of these conditions, photosynthesis cannot occur effectively.

What are the many unanswered questions of photosynthesis?

Use the search tool in the upper right (the magnifying glass) and you might find some. Narrow your search category down when looking for questions (botany, for example, and I'm not sure but there MIGHT very well be a category for photosynthesis.
