In order for respiration to occur, three things must be present: oxygen, a source of energy (such as glucose), and a metabolic system capable of breaking down the energy source to release energy for cellular processes.

Which structure supplies energy through aerobic respiration?

The mitochondria is the organelle responsible for supplying energy through aerobic respiration in cells. Within the mitochondria, the process of cellular respiration occurs, producing ATP through the breakdown of glucose in the presence of oxygen.


What is required for photosynthesis but not respiration?

Light is required for photosynthesis but not for respiration, as respiration can occur in the absence of light. Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen, while respiration breaks down glucose to release energy for cellular functions.


How do processes of photosynthesis and cellular respiration work together?

Photosynthesis provides glucose and oxygen in order for cellular respiration to occur.


Why do the cells of all living things carry out cellular respiration continuously?

Living things use energy in order to live, so we are constantly using converting ATP to ADP in order to get that energy. Cellular respiration replenishes the ATP by converting ADP back into ATP, which living things use for energy. Without cellular respiration an organism would die from lack of ATP, and therefore a lack of energy.


Does areboic respiration reqire oxygen to be present?

Yes, aerobic respiration requires oxygen to be present in order to produce ATP through the breakdown of glucose. Oxygen serves as the final electron acceptor in the electron transport chain, allowing for the efficient production of ATP.

What gas must be present for the aerobic breakdown of glucose to occur?

Oxygen gas must be present for the aerobic breakdown of glucose to occur. This process, known as cellular respiration, takes place in the mitochondria of the cell and generates energy in the form of ATP.


Is glucose a reactant in respiration?

Glucose must be present in order for cellular respiration to occur. Cellular respiration is the process in which glucose is broken down in to ATP (energy), Carbon Dioxide, and water. Glucose is a reactant in the sense that it must be present for the reaction to occur.

Does respiration occur at night?

Yes, of course =D. Cellular respiration must take place at all times in order to maintain functionality within a cell.

Which substances are needed for respiration?

During respiration, the main substances needed are oxygen and glucose. Oxygen is required for the process of cellular respiration, where glucose is broken down to produce energy in the form of ATP. Carbon dioxide and water are also byproducts of this process and are removed from the body.

Respiration releases what amount of energy Large or small?

Effective cellular respiration releases a large amount of energy (ATP). In order for effective cellular respiration to occur, oxygen must be present in the second stage of cellular respiration, the Krebs Cycle. If after the first stage of cellular respiration, glycolysis, there is no oxygen present, then ineffective cellular respiration occurs and the process is carried out by fermentation. Fermentation is an anaerobic process that results in the formation of ethyl alcohol or lactic acid and the cycle produces a net ATP gain of 2, whereas the net ATP gain of effective cellular respiration is 36 ATP molecules. Therefore cellular respiration in the presence of oxygen deals out a large amount of energy, but if not in the presence of oxygen, it deals out a small amount of energy.
