Why does cellular respiration depend on photosynthesis?
Cellular respiration needs glucose. Glucose is produced by photosynthesis
What does a cell need for photosynthesis?
A cell needs the products of cellular respiration, which is water and oxygen.
How do the processess of photosynthesis and cellular respiration work together?
both of which are released into the air during respiration. And during respiration, the plant needs oxygen and glucose, which are both produced through photosynthesis!
Can Krebs cycle occur in the dark?
Kreb's cycle is part of cellular respiration, it needs nothing but oxygen and glucose. Only photosynthesis needs light.
How does cellular respiration depend on photosynthesis?
Aerobic respiration requires oxygen to produce energy and expels carbon dioxide. This ultimately depends on photosynthesis, because plants take the carbon dioxide out of the air and use it for photosynthesis, which expels oxygen into the air as waste.
What organism uses cellular respiration for their cellular energy needs?
Most organisms, including animals, plants, fungi, and many bacteria, utilize cellular respiration to meet their energy needs. This process converts glucose and oxygen into ATP (adenosine triphosphate), carbon dioxide, and water. In animals, cellular respiration occurs primarily in the mitochondria, while plants also perform photosynthesis to produce glucose for respiration. Overall, cellular respiration is a fundamental metabolic pathway essential for life across various domains of organisms.
Do cellular respiration needs sunlight?
No, cellular respiration does not require sunlight. Cellular respiration is the process by which cells break down glucose to produce energy in the form of ATP, and it occurs in the presence of oxygen. Sunlight is needed for photosynthesis, which is the process by which plants produce glucose using sunlight, water, and carbon dioxide.
What does a plant has to do once it is dark in cellular respiration?
When it becomes dark, a plant continues to undergo cellular respiration to convert stored glucose into energy (ATP) for its metabolic processes. Unlike photosynthesis, which requires light, cellular respiration occurs continuously, utilizing oxygen to break down glucose. The byproducts of this process are carbon dioxide and water, which the plant can later use during photosynthesis when light is available again. Thus, even in darkness, plants rely on cellular respiration to meet their energy needs.
How would a loss of chlorophyll affect cellular respiration in plant cells?
A loss of chlorophyll in plant cells would reduce the amount of glucose produced through photosynthesis, which is a crucial energy source for cellular respiration. This would result in a decrease in the amount of substrate available for cellular respiration to produce ATP, impacting the overall energy production of the cell.
Explain the differences and similarities of photosynthesis and cellular respiration?
Photosynthesis only happens in plants and fungi, while respiration happens with animals. In the process of photosynthesis, plants take in CO2 and water and they produce oxygen and glucose. In the process of respiration, animals take in the oxygen and glucose that the plants produce and release CO2 and water, which the plants take in. This all fit to become a cycle, which is why we and plants support one another. In the night, however, plants perform the process of respiration instead of photosynthesis. The similarities that they have is that they are both processes that provide the needs of life to the different organisms.
What are the reactants and products of photosynthesis and cellular respiration?
Reactants carbon dioxide and water in:light energy + nCO2 + nH2O-->photosynthesis--> (CH2O)n + O2Reactants carbohydrate (n > 5 to 50.000, e.g. n=6: glucose) and oxygenreversed:(CH2O)n + O2-->respiration--> nCO2 + nH2O + 'green' energy
Why would a cell need to do photosynthesis and cell respiration?
A cell needs to do photosynthesis to convert sunlight into energy in the form of glucose. It then undergoes cell respiration to break down glucose and release stored energy for cellular processes. Together, photosynthesis and cell respiration maintain the cell's energy balance for growth, maintenance, and reproduction.
