Does cellular respiration not require light or photosynthesis?
Cellular respiration, on the other hand, is the process by which living things convert oxygen and glucose to carbon dioxide and water, thereby yielding energy. It does not require the presence of sunlight and is always occurring in living organisms. Cellular respiration takes place in the mitochondria of cells.
Does cellular respiration occur without light?
Explanation: Cellular respiration does not depend on light. The amount of light does indirectly affect cellular respiration by reducing the amount of glucose needed for cellular respiration. Cellular respiration goes on inside of plant cells, regardless if light is shinning on the plant or not.
Which part of photosynthesis does not require light?
The light-independent stage, also known as the Calvin Cycle, takes place in the stroma, the space between the thylakoid membranes and the chloroplast membranes, and does not require light, hence the name light-independent reaction.
Does photosynthesis require light?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.
What is the difference of photosynthesis and cellular respiration?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
What is similar between photosynthesis and cellular respiration?
Photosynthesis and cellular respiration are two biochemical processes that are essential to most life on Earth. Both of these processes involve multiple complex steps and many of the same molecules—oxygen (O2), carbon dioxide (CO2), water (H2O), glucose (C6H12O6), and adenosine triphosphate (ATP).
Does cellular respiration occur in sunlight?
Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. Plants would release energy through cellular respiration in times when sunlight is not present.
What role does oxygen play in photosynthesis and cellular respiration?
What roles does oxygen play in photosynthesis and in cellular respiration? Photosynthesis releases oxygen into the atmosphere as a. product, whereas cellular respiration uses oxygen as a reactant to release energy from food.
What light is needed for photosynthesis?
The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.
How light is used in photosynthesis?
The process of photosynthesis occurs when green plants use the energy of light to convert carbon dioxide (CO2) and water (H2O) into carbohydrates. Light energy is absorbed by chlorophyll, a photosynthetic pigment of the plant, while air containing carbon dioxide and oxygen enters the plant through the leaf stomata.
Is it possible for photosynthesis to occur without cellular respiration?
Photosynthesis cannot occur without cellular respiration and cellular respiration certainly cannot occur without the photosynthesis. Photosynthesis and cellular respiration are in many respects the reverse of one another. Photosynthesis is an anabolic process, whereas cell respiration is a catabolic process.
How are light and dark reactions related in photosynthesis?
Hence in photosynthesis you have the light dependent reactions and the dark reactions while in respiration there is aerobic respiration and anaerobic respiration. In photosynthesis light dependent reactions, ultra violet light strikes chlorophyll pigments which excites electrons leading to separation of oxygen molecules from carbon dioxide.
Photosynthesis and respiration are reactions that complement each other in the environment. They are in reality the same reactions but occurring in reverse. While in photosynthesis carbon dioxide and water yield glucose and oxygen, through the respiration process glucose and oxygen yield carbon dioxide…
What are the 4 stages of photosynthesis in the cell?
4 stages: Glycolysis, Linking Reaction (pyruvate oxidation), Krebs cycle, Electron Transport Chain (oxidative phosphorylation). 2 stages: The light dependent reaction, light independent reaction.
