Is photosynthesis faster than cellular respiration?

You may be wondering how plants produce oxygen for us to breathe when they have to use it themselves for cellular respiration. Well, the rate of photosynthesis is usually faster than respiration, so a plant produces more oxygen than it needs for itself.

Why is photosynthesis better than cellular respiration?

While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. Cellular respiration works best in the presence of oxygen. Without oxygen, much less ATP would be produced. Cellular respiration and photosynthesis are important parts of the carbon cycle.

Is cellular respiration fast or slow?

Cellular respiration actually “burns” glucose for energy. However, it doesn’t produce light or intense heat like burning a candle or log. Instead, it releases the energy slowly, in many small steps. The energy is used to form dozens of molecules of ATP.

What are differences between 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 an outcome from a lack of oxygen?

Brain cells are very sensitive to a lack of oxygen. Some brain cells start dying less than 5 minutes after their oxygen supply disappears. As a result, brain hypoxia can rapidly cause severe brain damage or death.

What is the difference between glycolysis and cellular respiration?

Glycolysis is catabolic; it breaks down glucose, a 6 carbon sugar into pyruvate, a 3 carbon sugar. Glycolysis is unique because it is completely anaerobic – meaning it doesn’t require oxygen and will proceed with or without it. Unlike the next steps in cellular respiration, which absolutely require oxygen to occur.
