Photosynthesis occurs in two main stages: the light-dependent reactions and the light-independent reactions (Calvin cycle). In the light-dependent reactions, sunlight is captured by chlorophyll, leading to the production of ATP and NADPH, while splitting water molecules to release oxygen. In the Calvin cycle, ATP and NADPH are used to convert carbon dioxide into glucose through a series of enzymatic reactions. Together, these processes enable plants to synthesize glucose from light energy.
What else can I help you with?
Which of these is not needed for photosynthesis A chlorophyll B sunlight C oxygen D glucose E water?
Oxygen and glucose is not needed for photosynthesis. Technically, water is needed only to keep the plant alive but, like oxygen and glucose, it does not play a role in photosynthesis. Sunlight IS needed, and chlorophyll must be present to absorb the sunlight.
What happens during the Calvin Benson cycle?
In the Calvin-Benson cycle, also known as the light-independent reactions of photosynthesis, carbon dioxide is fixed and converted into sugars using energy from ATP and NADPH generated in the light-dependent reactions. This process involves a series of enzymatic reactions that ultimately produce glucose, the primary product of photosynthesis, and regenerate the molecules needed to continue the cycle.
Sodium hydroxide removes a gas that is needed for photosynthesis what is the gas?
The gas that is removed by sodium hydroxide and is needed for photosynthesis is carbon dioxide (CO2). This gas is essential for plants to produce glucose through the process of photosynthesis.
Are the products of photosynthesis the raw materials of cellular respiration?
Photosynthesis: carbon dioxide + water (+ sunlight) -------> oxygen + glucose Aerboic Respiration: oxygen + glucose ------> carbon dioxide + water (+ energy) So yes the products of photosynthesis are the raw materials of AEROBIC respiration.
Where do plants get glucose and oxygen needed for respiration?
Plants produce glucose through photosynthesis, where they convert sunlight, water, and carbon dioxide into glucose and oxygen. The glucose produced is used for energy through respiration, where oxygen is taken in from the surrounding environment and glucose is broken down to release energy.
What is the relationship between the light and dark reactions in photosynthesis?
The light reactions in photosynthesis capture sunlight to produce energy in the form of ATP and NADPH, which are then used in the dark reactions to convert carbon dioxide into glucose. In other words, the light reactions provide the energy needed for the dark reactions to occur and produce sugar.
What pigment is needed to carry out the chemical reactions of photosynthesis?
Chlorophyll is the main pigment needed to carry out the chemical reactions of photosynthesis. It absorbs light energy from the sun and converts it into chemical energy that is used by the plant to produce glucose.
What compound is needed for photosynthesis?
The compound needed for photosynthesis is carbon dioxide (CO2). During the light-dependent reactions of photosynthesis, CO2 is taken in by the plant through small openings called stomata on the leaves. This CO2 is then used in the Calvin cycle, also known as the light-independent reactions, to produce glucose and other organic compounds essential for plant growth and development.
Is hydrogen needed in plant growth?
Yes, it is required during photosynthesis to produce glucose
What is the role of water in photosynthesis and how does it contribute to the overall process?
Water plays a crucial role in photosynthesis by providing the necessary electrons for the light-dependent reactions. During this process, water molecules are split into oxygen, protons, and electrons. The electrons are then used to produce energy in the form of ATP and NADPH, which are essential for the synthesis of glucose in the light-independent reactions. In summary, water is essential for photosynthesis as it provides the electrons needed to generate energy and ultimately produce glucose, the main product of photosynthesis.
What are the dark reactions?
It is photosynthesis where light is not needed. It is a nickname for the Calvin-Benson cycle which is the second main step of photosynthesis. It utilizes the ATP and NADPH produced from the light-reactions as well as carbon dioxide from the air in order to produce glucose.
Which of these is not needed for photosynthesis A chlorophyll B sunlight C oxygen D glucose E water?
Oxygen and glucose is not needed for photosynthesis. Technically, water is needed only to keep the plant alive but, like oxygen and glucose, it does not play a role in photosynthesis. Sunlight IS needed, and chlorophyll must be present to absorb the sunlight.
Light depends on reactions of photosynthesis produce ATP and nadph but they are not in the overall final reaction that is written out for photosysnthesis why?
While the products of the light reactions, ATP and NADPH, are not explicitly shown in the overall chemical equation for photosynthesis, they are crucial for the dark reactions (Calvin cycle) where they provide the energy and reducing power needed to convert carbon dioxide into glucose. The overall equation for photosynthesis simplifies the process and highlights the conversion of carbon dioxide and water into glucose and oxygen.
What happens during the Calvin Benson cycle?
In the Calvin-Benson cycle, also known as the light-independent reactions of photosynthesis, carbon dioxide is fixed and converted into sugars using energy from ATP and NADPH generated in the light-dependent reactions. This process involves a series of enzymatic reactions that ultimately produce glucose, the primary product of photosynthesis, and regenerate the molecules needed to continue the cycle.
What plant is needed for photosynthesis?
The question makes no sense. Plants require water, sunlight and carbon dioxide in order to produce glucose through photosynthesis
How do the reactions and Calvin cycle work together to build glucose?
The light reactions provide the energy carriers used in the Calvin cycle
Why is water important for photosynthesis and how does it contribute to the process?
Water is important for photosynthesis because it serves as a source of hydrogen atoms and electrons needed for the production of glucose. During photosynthesis, water molecules are split into oxygen, hydrogen ions, and electrons through a process called photolysis. The electrons and hydrogen ions are then used in the light-dependent reactions of photosynthesis to produce energy-rich molecules that drive the synthesis of glucose. In summary, water is essential for photosynthesis as it provides the necessary components for the production of glucose, the main product of photosynthesis.
