Describe about hormones and enzyme

Enzymes

Hormones

Catalyst: Accelerates the rate of a reaction

Messenger: Triggers functions in the body

Predominantly composed of proteins

Composed of proteins, amino acids, steroids etc

Retains chemical make-up after use, hence can be reused

Chemical composition changes after use, hence cannot be reused

External factors acutely affect regulation of enzymes such as temperature, pH levels etc

External factors do not affect hormones as acutely as enzymes.

Enzymes cannot diffuse through a cell membrane

Hormones can diffuse through a cell membrane

Exocrine glands produce Enzymes

(salivary glands, sweat glands)

Endocrine glands produce Hormones

(thyroid and pituitary glands)

Enzymes are not affected by age

Hormones are affected by age (puberty)

Enzymes form and act at the site of production

Hormones form and act at different sites

Examples: Protease, amylase, and lipase are important enzymes for digestion

Examples: Melatonin is the hormone that regulates your circadian rhythm (sleep cycle)

Insulin is another hormone that regulates blood sugar
