Study Notes

Enzymes and Acid/Bases

Enzymes are biological catalysts that speed up reactions in the body, including digestion, metabolism, and energy production.
Lipase breaks down fats.
Amylase breaks down carbohydrates, specifically starches.
Lactase breaks down lactose in milk and dairy products.
Protease breaks down proteins into amino acids.

Optimal pH

Each enzyme works best at a specific pH level, called its optimal pH.
If the pH is too high or too low, the enzyme may not work as well or may stop working completely.
Testing pH levels in food is important for production and digestion.

pH Scale

The pH scale measures acidity and basicity.
It ranges from 0 to 14.
pH < 7: Acidic
pH = 7: Neutral
pH > 7: Basic

Properties of Acids

Sour taste
Turns blue litmus paper red
Reacts with metal

Properties of Bases

Bitter taste
Feels slippery and soapy
Turns red litmus paper blue
Known as alkaline
