Understanding and Influencing Factors

KOMPAS.com – Most of the energy flow through the biosphere begins with photosynthesizing organisms.

Then, some of that energy is obtained by organisms, including animals, which eat photosynthetic organisms (called herbivores), which in turn are consumed by other organisms including animals (carnivores) or by organisms that eat dead organisms (decomposers) to obtain their energy, growth, reproduction. , and other functions.

Oxygen that is inhaled during breathing and enters the body will be used to respiration process mobile.

Cellular respiration uses organic molecules from food, such as sugar and oxygen, to produce energy stored in adenosine triphosphate (ATP) molecules, as well as heat.

Reported from University of California, Besides that, cellular respiration It also produces carbon dioxide and water.

Cellular respiration developed after the early photosynthetic bacteria began to provide a stable and abundant source of oxygen, after which oxygen began to accumulate in the ocean and atmosphere.

Anaerobic Respiration

The earliest life forms, and some bacteria today, used only anaerobic processes (respiration without oxygen) to produce energy.

Anaerobic processes, including fermentation, also occur in organisms that use cellular respiration, such as in human muscles, but these anaerobic processes do not produce energy as efficiently as the aerobic pathway.

Bacteria that use anaerobic respiration also live in the stomachs of animals, such as cows and sheep, and help break down the grass they eat.

The by-product of this anaerobic process is methane (CH4).
