How is light energy transformed into chemical energy during photosynthesis?

User Avatar

Asked by Wiki User

Photophosphorylation is the process of creating ATP using a Proton gradient created by the Energy gathered from sunlight. The process of creating the Proton gradient resembles that of the electron transport chain of Respiration. But since formation of this proton gradient is light-dependent, the process is called Photophosphorylation.

Chemiosmosis - Chemiosmosis is the process of using Proton movement to join ADP and Pi. This is accomplished by enzymes called ATP synthases or ATPases. The CF1-ATPase of the Thylakoid membrane is shown on the left (DIAGRAM IN LINK). As protons pass through this enzyme ADP and Pi are joined to make ATP. The movement of the Protons through this enzyme provides the Energy needed to make ATP

What are the similarities between respiration and combustion?

User Avatar

Asked by Wiki User

Both respiration and combustion involve the process of breaking down molecules to release energy by combining oxygen and fuel. They both produce carbon dioxide and water as byproducts. In both processes, energy is released in the form of heat.

The Product of photosynthisis?

User Avatar

Asked by Wiki User

The products of photosynthesis are glucose (sugar) and oxygen. In the presence of sunlight, plants convert carbon dioxide and water into glucose, which can be used as energy for the plant, and release oxygen as a byproduct into the atmosphere.

How do plants use visible light in photosynthesis?

User Avatar

Asked by Wiki User

Plants use visible light in photosynthesis by absorbing it through pigments like chlorophyll in their chloroplasts. This light energy is then converted into chemical energy in the form of glucose, through a series of biochemical reactions, which serves as fuel for the plant's growth and development.

Which process is the major source of oxygen released into the atmosphere?

User Avatar

Asked by Wiki User

Photosynthesis is the major process that produces and releases oxygen into the atmosphere. This process occurs in plants, algae, and some bacteria, where they convert carbon dioxide and water into oxygen and glucose using sunlight as energy. Approximately half of the oxygen in Earth's atmosphere is produced through photosynthesis.

What is raw materials of photosynthesis?

User Avatar

Asked by Wiki User

The raw materials of photosynthesis are water and carbon dioxide. Water is absorbed by the roots of the plant and transported to the leaves, while carbon dioxide is taken in from the air through small openings called stomata on the leaves. These two materials are used by the plant, along with sunlight, to produce oxygen and glucose.

What things are needed for photosynthesis?

User Avatar

Asked by Wiki User

Photosynthesis requires sunlight, carbon dioxide, and water. These three elements are essential for the process to occur, resulting in the production of glucose and oxygen by plants.

What portions of the visible spectrum benefit photosynthesis the most?

User Avatar

Asked by Wiki User

Plants benefit most from the blue (400-500 nm) and red (600-700 nm) portions of the visible spectrum for photosynthesis. These wavelengths are absorbed by chlorophyll a and b, the pigments responsible for capturing light energy for photosynthesis. Green light (500-600 nm) is least effective for photosynthesis as it is reflected, giving plants their green color.

A substance that acts as a catalyst during photosynthesis is?

User Avatar

Asked by Wiki User

The substance that acts as a catalyst during photosynthesis is an enzyme called Rubisco. Rubisco plays a key role in the carbon fixation process, where it catalyzes the reaction that combines carbon dioxide and ribulose-1,5-bisphosphate to form 3-phosphoglycerate in the Calvin cycle.

What chemicals are produced during photosynthesis?

User Avatar

Asked by Wiki User

The main chemicals produced during photosynthesis are glucose (sugar) and oxygen. Glucose is a type of carbohydrate that stores energy and is used as a source of food for the plant. Oxygen is released as a byproduct of the process and is crucial for respiration in plants and animals.

Differentiate anabolism and catabolism?

User Avatar

Asked by Wiki User

Anabolic pathway is the set of metabolic pathways that construct molecules from smaller units ie, it is constructive in nature while catabolic pathway is the set of metabolic pathways that break down molecules into smaller units and release energy ie, they are destructive in nature.

During photosynthesis visible light has enough energy to?

User Avatar

Asked by Wiki User

During photosynthesis, visible light has enough energy to excite electrons in chlorophyll molecules within the chloroplasts of plant cells. This excitation of electrons allows them to undergo a series of reactions that eventually produce ATP and NADPH, which are essential for the synthesis of glucose and other organic compounds.

What is NADP an abbreviation for?

User Avatar

Asked by Wiki User

NADP stands for Nicotinamide Adenine Dinucleotide Phosphate.

Photosynthesis is an example of which type of nutrition?

User Avatar

Asked by Wiki User

Photosynthesis is an example of autotrophic nutrition, as plants are able to produce their own food using sunlight, water, and carbon dioxide.

What does the word sterols mean?

User Avatar

Asked by Wiki User

Sterols are a type of lipid that are found in plants and animals, and they play important roles in cell membrane structure and function. Cholesterol is a well-known sterol found in animals, while phytosterols are the primary type found in plants. Sterols are important for maintaining cell integrity and are also precursors for the synthesis of important molecules like hormones.

True or False Photosynthesis the use of sunlight to make food occurs in the oceans?

True. Photosynthesis occurs in the oceans among marine plants, algae, and phytoplankton which use sunlight to convert carbon dioxide and water into organic compounds, producing oxygen as a byproduct.

Compare photosynthesis with respiration?

User Avatar

Asked by Wiki User

Photosynthesis is a process in which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen. Respiration, on the other hand, is the process by which cells break down glucose to produce energy, carbon dioxide, and water. They are interconnected processes: the oxygen produced during photosynthesis is used in respiration, and the carbon dioxide produced during respiration is used in photosynthesis.

Which gas is converted by plants using light energy through the process of photosynthesis?

User Avatar

Carbon dioxide (CO2) is the gas converted by plants using light energy through the process of photosynthesis.

What is the relationship between the chemical equation for photosynthesis and the chemical equation for cellular respiration?

User Avatar

Asked by 2da2ny2

The chemical equation for photosynthesis is the opposite of the chemical equation for cellular respiration. In photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen in the presence of sunlight, while in cellular respiration, organisms use glucose and oxygen to produce carbon dioxide, water, and ATP for energy. Together, these processes form a cyclic relationship where the products of one process are used as reactants in the other.

What are the requirements for photosynthesis?

User Avatar

Asked by Wiki User

Photosynthesis requires sunlight, water, and carbon dioxide. Water and sunlight are used during the light reaction (in the presence of Chlorophyll), and carbon dioxide is used in the Calvin Benson Cycle (Dark reaction).

_____________________________________________________________________

Equation of photosynthesis:

Sunlight.............................

6CO2 + 6H20 → C6H12O6 + 6O2

..............Chlorophyll.......................

_____________________________

..................................Sunlight...........................

Carbon Dioxide + Water → Glucose + Oxygen

................................Chlorophyll..........................

Since the Oxygen liberated during photosynthesis comes from water and a number of enzymes are required to do the job the chemical equation for photosynthesis should be as under-

6CO2 + 12 H2O (in a living Choloroplast using sunlight) = C6H12O6 + 6H2O + 6O2

Can leaves that are not green make food?

User Avatar

Asked by Wiki User

Yes, leaves that are not green can still photosynthesize and make food. Some leaves, such as those with red or purple pigments, have adapted to produce food using different wavelengths of light. These leaves may have different pigments that capture sunlight and can still convert it into energy for the plant.

Examples of Nonvascular?

User Avatar

Asked by Wiki User

Examples of nonvascular plants include mosses, liverworts, and hornworts. These plants lack specialized tissues for transporting water and nutrients, so they are typically found in damp environments where they can absorb water directly from their surroundings. Nonvascular plants reproduce through spores rather than seeds.

How go photosynthesis and respiration work together in the biosphere?

User Avatar

Asked by Wiki User

Photosynthesis and respiration are interconnected processes in the biosphere. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen, while respiration involves the breakdown of glucose to produce energy, carbon dioxide, and water. These processes are complementary, as photosynthesis releases oxygen that is used in respiration, and respiration releases carbon dioxide that is used in photosynthesis. Together, they play a critical role in the cycling of carbon and oxygen in the biosphere.
