Cellular Respiration

Cellular Respiration Definition

Cellular Respiration is a vital process that occurs in living things. It is a process by which cells turn nutrients into adenosine triphosphate (ATP), which is their source of energy....

What is Cellular Respiration?

One of the basic processes in living things’ cells is called cellular respiration, which turns nutrients into adenosine triphosphate (ATP), the energy source for the cells. Glycolysis, the Krebs cycle (also referred to as the citric acid cycle or tricarboxylic acid cycle), and oxidative phosphorylation (which includes the electron transport chain) are the three primary phases of this process....

Cellular Respiration Examples

A basic mechanism found in all cell types, from simple bacteria to complex multicellular organisms, is cellular respiration. Here are some examples of several organism’ cellular respiration:...

Steps of Cellular Respiration

The breakdown of a glucose molecule into CO2 and H2O occurs gradually during cellular respiration. Along the process, the processes that change glucose directly create some ATP. However, a procedure known as oxidative phosphorylation produces a lot more ATP later on. The electron transport chain, a collection of proteins positioned in the inner membrane of the mitochondrion, is the engine driving oxidative phosphorylation....

Types of Cellular Respiration

Anaerobic and aerobic respiration are the two primary forms of cellular respiration. The availability of oxygen is the main difference between them. Below is a summary of each kind:...

Why Do We Respire?

In all living things, including humans, respiration is a basic physiological mechanism that performs a number of vital tasks. The main functions of respiration are to eliminate carbon dioxide (CO2), a waste product of cellular metabolism, and supply the body with oxygen (O2) on a constant basis. The two primary forms of respiration are cellular or internal respiration and external respiration....

Importance of Cellular Respiration

Living things depend heavily on cellular respiration for a number of vital processes that are necessary for life sustenance. Cellular respiration is significant for the following main reasons:...

Conclusion – Cellular Respiration

In conclusion, the process of cellular respiration is essential for the synthesis of ATP, the principal energy unit of the cell. While the Krebs cycle and oxidative phosphorylation are aerobic processes that require oxygen, glycolysis may occur in both anaerobic and aerobic environments. Cells may ferment in the absence of oxygen in order to replenish NAD+ and carry out glycolysis. When oxygen is present, aerobic respiration takes place, which is a more efficient mechanism that produces more ATP. Contrarily, anaerobic respiration takes place in the absence of oxygen and uses less effective processes such the fermentation of lactic acid or alcohol....
