Cellular Respiration

is the process by which cells convert glucose and oxygen into energy (ATP), water, and carbon dioxide.

Mitochondria

are the powerhouse of the cell, where cellular respiration occurs, producing ATP from energy-rich molecules.

ATP

Direct energy source for cells 

Aerobic Respiration 

is a type of cellular respiration that requires oxygen to produce ATP, water, and carbon dioxide from glucose.

Anaerobic Respiration

is a type of cellular respiration that occurs without oxygen, resulting in the production of ATP and byproducts such as lactic acid or ethanol.

Lactic Acid Fermentation

is a metabolic process that occurs in anaerobic conditions, where glucose is converted into ATP and lactic acid, commonly used by muscle cells during intense exercise.

Homeostasis

is the process by which biological systems maintain a stable internal environment despite external changes.

Feedback Loop

is a biological mechanism in which the output of a process regulates its own production, helping to maintain homeostasis within the body.
