Protease and Proteins

Protease enzymes are essential for breaking down the proteins we eat into amino acids for growth and repair.

Which organ produces a protease that works in acidic conditions?

What is Protease and Proteins?

"Proteases are enzymes that break down proteins into their constituent amino acids."

Question 1

Proteases break down proteins into which smaller molecules?

Question 2

Proteases break down proteins into which smaller molecules?

Question 3

Proteases break down proteins into which smaller molecules?

Protein Breakdown

Proteases break down proteins into amino acids.

Produced in the stomach (pepsin), pancreas, and small intestine.

Amino acids are then absorbed into the bloodstream.

Exam Tip

The stomach produces hydrochloric acid specifically to provide the optimum pH for protease.
