Accepted Answer

### Question 2
# Brief Explanations:
Enzymes bind to substrates (the reactants they act on) to catalyze reactions, not products (which are the end results).
# Answer:
substrates

### Question 3
# Brief Explanations:
Amylase is the enzyme that breaks down starch (a polysaccharide) into smaller sugars. Catalase breaks down hydrogen peroxide, not starch.
# Answer:
amylase

### Question 4
# Brief Explanations:
Enzymes are reusable because they are not consumed in the reaction; they can bind to new substrates after releasing products.
# Answer:
are

### Question 5
# Brief Explanations:
Enzymes are biological catalysts, and catalysts speed up chemical reactions by lowering activation energy.
# Answer:
speed up

### Question 6
# Brief Explanations:
Lactase is a specific enzyme that breaks down lactose (a disaccharide) into glucose and galactose (simple sugars). It does not break down products (which are the result of a reaction).
# Answer:
lactose

### Question 7
# Brief Explanations:
When an enzyme and substrate bind, the temporary complex formed is called the enzyme - substrate complex. A product is the result of the reaction, not the intermediate complex.
# Answer:
complex

### Question 8
# Brief Explanations:
Adding more substrate provides more molecules for the enzyme to act on, so the reaction will continue (and speed up until enzyme saturation, but it won't stop just from adding more substrate).
# Answer:
continue

### Question 9
# Brief Explanations:
Adding more enzyme provides more active sites for substrate binding, so the reaction will continue (and speed up as long as there is sufficient substrate).
# Answer:
continue

### Question 10
# Brief Explanations:
Enzymes are crucial in digestion (e.g., amylase in saliva, proteases in the stomach/intestines) to break down food. While reproduction has enzymatic processes, digestion is a more direct and well - known life process heavily dependent on enzymes for breaking down nutrients.
# Answer:
digestion
