Glands are made of GLANDULAR TISSUE, which can produce substances such as Enzymes and Hormones.
The two glands we need to know:
1) Salivary Gland - Secretes Amylase - (starch into sugars)
2) Pancreas - Secretes Amylase, Trypsin and Lipase (T= Protein into amino acids, L= Lipids into fatty acids & glycerol)
The stomach contains glandular tissue. It secretes Pepsin. The small intestine secretes proteases, lipases and amylase
WHAT ARE ENZYMES?
Proteins that act as biological catalysts.
They have an ACTIVE SITE that is specific to the substrate. The enzyme & substrate collide & the products are formed. The enzyme can be REUSED.
They are denatured at high temperatures
