Recall that proteases break proteins down into amino acids.

Recall that proteases break proteins down into amino acids. The human digestive system sits within Animal tissues, organs and organ systems, so this idea should be explained in that specific biological context rather than as an isolated phrase. A useful term here is protease, because protease is a curriculum-aligned term linked to the learning objective: Recall that proteases break proteins down into amino acids. Avoid giving a vague answer instead of directly addressing: Recall that proteases break proteins down into amino acids; instead answer by clearly explaining how to recall that proteases break proteins down into amino acids. Use precise biological vocabulary when you explain how to recall that proteases break proteins down into amino acids. This keeps your answer tightly aligned to the approved learning objective for The human digestive system.
