As light passes through the cornea and lens, refraction takes place at varying degrees depending on lens shape. Objects closer to the eye have diverging light rays, thus need more refraction from the lens...

Enzymes are biological catalysts that hydrolyse chemical bonds in biological molecules, such as lipids. Enzymes are important in digestion, as they aid the absorption of molecules across the lumen of the ...

Anaerobic respiration in yeast cells produces carbon dioxide and ethanol. Whereas anaerobic respiration in muscle cells produces lactic acid only.Both, however, do produce little amounts of ATP (energy)

This process is called Ventilation and is a required step in aerobic respiration.This process starts with the diaphragm contracting, one also sees the (external) intercostal muscles contract. These contra...

The role of enzymes such as proteases and lipases in the body is to break down proteins and fats respectively during digestion. Proteins are broken down into amino acids and fats are broken down into fatt...
