Which role does photosynthesis play in the flow of energy?
Photosynthesis has a role in the cycling of matter and flow of energy into and out of organisms. The flow of energy and cycling of matter can be traced. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur.
How do plants metabolize energy?
Photosynthesis is the first step in converting light energy to biomass in the light but plants also grow at night in darkness. For this, biochemical energy is stored in form of starch and carbohydrates. This requires an accurate coordination of growth and plant primary metabolism which also involves the inner clock.
How is respiration related to metabolism?
Cellular respiration, which takes place within cells, consists of the metabolic processes by which energy is obtained by breaking down glucose through enzymatic pathways (glycolysis and the Krebs cycle), creating water, carbon dioxide and ATP. Respiration responds directly to metabolic needs.
How is photosynthesis important to catabolism?
How is photosynthesis important to catabolism? It is the synthesis of complex organic compounds from simple inorganic substances that can later be used for catabolism in cellular respiration.
How do organisms make food?
The majority of life on the planet is based on a food chain which revolves around sunlight, as plants make food via photosynthesis. However, in environments where there is no sunlight and thus no plants, organisms instead rely on primary production through a process called chemosynthesis, which runs on chemical energy. Together, photosynthesis and chemosynthesis fuel all life on Earth.
What is the energy used in photosynthesis?
All photosynthetic organisms use solar energy to turn carbon dioxide and water into sugar (food) and oxygen: 6CO 2 + 6H 2 O -> C 6 H 12 O 6 + 6O 2. Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food.
Where are chemosynthetic communities found?
Since then, chemosynthetic bacterial communities have been found in hot springs on land and on the seafloor around hydrothermal vents, cold seeps, whale carcasses, and sunken ships. No one had ever thought to look for them, but these communities were there all along.
What is the cycle of photosynthesis and respiration?
Occurs in…. The cycle of photosynthesis and respiration maintains the balance of oxygen and carbon dioxide. Photosynthesis produces the oxygen to replenish oxygen that is used up by living organisms during respiration. Carbon dioxide produced during respiration is one of the reactants plants need to perform photosynthesis.
What is the oxygen produced by plants during photosynthesis?
The oxygen produced by plants during photosynthesis is what humans and animals inhale for the blood to transport to the cells for respiration . The carbon dioxide produced during respiration is released from the body and absorbed by plants to help provide the energy they need for growth and development.
What is the relationship between photosynthesis and cellular respiration?
The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.
What is the never ending cycle of life?
This is the never ending cycle that sustains life on earth.
