pd: ____ date: __5.6 enzyme function in the bodypart 1: do nowwhat do you think is responsible for this chemical breakdown? what are the basic components of these complex carbohydrates?part 2: how enzymes work - video notes1. what is the job of an enzyme in a chemical reaction?to break down complex2. why dont enzymes get used up during a reaction?3. match each enzyme to its function:| enzyme | function || ---- | ---- || a. amylase | __ breaks down fats in the small intestine || b. lipase | __ breaks down proteins in the stomach || c. pepsin | __ breaks down carbohydrates in saliva |4. for each factor below, explain how it affects enzyme function:a. temperature: ___________b. ph (acidity/alkalinity): ___________c. enzyme concentration: _____________

Explanation:

Part 1:

Enzymes (like amylase) drive complex carbohydrate breakdown; complex carbs are made of monosaccharides (e.g., glucose).

Part 2:

1. Enzymes lower reaction activation energy to speed up reactions (the partial answer is incomplete; this is the full job).
2. Enzymes are catalysts that remain chemically unchanged, so they are reused.
3. Match each enzyme to its known biological function: amylase acts on carbohydrates in saliva, lipase breaks down fats in the small intestine, pepsin breaks down stomach proteins.
4. A. Temperature: Enzymes have an optimal temperature; too low slows activity, too high denatures them, stopping function.

B. pH: Each enzyme has an optimal pH; deviations denature the enzyme, reducing or stopping function.
C. Enzyme Concentration: Higher concentration speeds reaction rate (until substrate is limited), as more active sites are available.

Answer:

Part 1:

Enzymes (specifically carbohydrate-digesting enzymes like amylase) are responsible for the chemical breakdown of complex carbohydrates. The basic components of complex carbohydrates are monosaccharides (simple sugars such as glucose).

Part 2:

1. To lower the activation energy of the reaction, speeding it up (without being consumed).
2. Enzymes are biological catalysts; they are not chemically altered during the reaction, so they can be reused.

3.

Enzyme	Function
B. Lipase	Breaks down fats in the small intestine
C. Pepsin	Breaks down proteins in the stomach

4.
A. Temperature: Low temp slows enzyme activity; optimal temp maximizes it; high temp denatures enzymes, stopping function.
B. pH (Acidity/Alkalinity): Enzymes have an optimal pH; moving outside this range denatures enzymes, reducing their function.
C. Enzyme Concentration: Higher enzyme concentration increases reaction rate (until substrate runs out), as more active sites are available for substrates.
