Factors Responsible For The Varied Supply Of ATP During Cellular respiration
For life to survive, it needs to be sustained with nutrients. Nutrients serve multiple functions in the body of different organisms, one of which is to supply energy. Energy giving nutrients supply the body with chemical energy which is trapped inside adenosine triphosphate or ATP. The process by which ATP is created can be summarized as digestion and cellular metabolism. When living organisms ingest food into their alimentary canal, these items are broken down into their simple forms that can be absorbed by cells and utilized for different cellular activities. The production of energy exists as an example of these cellular activities, from which ATP is produced.
This energy expelled by several metabolic pathways is stored inside an element called ATP that is then used as an energy source for every cellular activity. In the presence of oxygen, ATP is created via a set of processes called cellular respiration, where its major site of production is in an organelle known as mitochondria.
Although some amounts of ATP are produced at other parts of the cell-like in the cytoplasm, the main supply of ATP comes from the mitochondria, which got it its alias as the powerhouse of the cell. For a single round of cell respiration cycle about 30 to 40 ATPs are created per turn, the variance in creation is defined by different factors. Types of fuel sources determine greatly how many ATP will be produced for every metabolic cycle.
Theoretically, fats produce the highest amount of ATP, about 40 ATPs in total, while protein and carbs source produce a lesser amount of ATP. The cell type also affects the number of ATP created, since the efficiency of energy generation differs from each cell type. Muscle cells and Brain cells are more efficient in producing ATP than other types of cells. The efficiency of production of ATP differs, there are times protons tasked with driving the creation of ATP leak inside without passing through an ATP synthase.
