Does photosynthesis expend energy?
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
Is there more respiration than photosynthesis?
Overall, photosynthesis (oxygen production) is higher than the rate of respiration in plants during a year. Aerobic respiration continues all the time in plant cells (in light and in darkness), using up oxygen and making carbon dioxide.
What is the main difference between photosynthesis and respiration?
Differences between Cellular Respiration and Photosynthesis
|In this process, food particles are broken down to release energy.||In this process, food is synthesized by capturing energy.|
|It is an exergonic reaction as energy is released.||It is an endothermic reaction as it requires energy.|
Does photosynthesis and cellular respiration produce ATP?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP.
How are cellular respiration and photosynthesis similar to and different from each other?
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.
Why does the respiration rate increase as photosynthesis increases in a leaf?
The compensation point
So the rate of respiration is greater than the rate of photosynthesis. … This means more carbon dioxide is being absorbed by the plant for photosynthesis. So this means more carbon dioxide uptake occurs. The graph shows this increase in carbon dioxide uptake.
Does respiration release energy?
Respiration is the chemical process by which organic compounds release energy. The compounds change into different ones by exergonic reactions. The hydrolysis of adenosine triphosphate (ATP) to adenosine diphosphate (ADP) and phosphoric acid (Pi) releases energy (it is an exergonic reaction).
What happens when photosynthesis exceeds respiration?
When the rate of photosynthesis exceeds the rate of respiration, plants grow. If respiration exceeds photosynthesis, then growth declines, photosynthate reserves are used, and plants become more susceptible to biotic and abiotic stresses.
What are 3 differences between respiration and photosynthesis?
Respiration is something that occurs in all living organisms. Thus, it is a process that converts oxygen and glucose into carbon dioxide and water and ultimately makes energy for your body cells.
Difference between Photosynthesis And Respiration.
|Basis of Comparison||Photosynthesis||Respiration|
|Chemical reaction||6CO2 + 6H2O → C6H12O6 + 6O2||C6H12O6 + 6O2 → 6CO2 + 6H2O|
What is the similarity between photosynthesis and respiration?
Both photosynthesis and respiration involve the conversion of energy from one form to another through a series of biochemical reactions. Both processes use and produce ATP in reactions that are carried out on membranes and are controlled by enzymes.
What is the difference between the breathing and respiration?
Breathing and respiration are two completely different but interrelated body processes which assist body organs to function properly. Breathing is the physical process of exchanging gases whilst respiration is a chemical process which takes place at a cellular level and produces energy.
Why is photosynthesis faster than cellular respiration?
The cell uses oxygen and glucose to create water, carbon dioxide, and energy. … Well, the rate of photosynthesis is usually faster than respiration, so a plant produces more oxygen than it needs for itself.
Why is photosynthesis more important than cellular respiration?
Photosynthesis serves as the primary source of energy in plants while cellular respiration breaks down the glucose in the cell to provide energy to carry out life processes.
Why is that aerobic respiration more efficient than anaerobic respiration?
A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can split glucose into just two molecules of pyruvate. … This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.
