Question

Accepted Answer

### Question 2
# Brief Explanations:
Proteases (enzyme "A") act on protein substrates. So if enzyme "A" (protease) fits a substrate, that substrate is a protein.
# Answer:
If enzyme "A" (protease) fits with substrate (a protein - related substrate, e.g., a protein molecule), the substrate would be a **protein**.

### Question 3
# Brief Explanations:
Maltase is an enzyme that specifically acts on maltose (a disaccharide). So maltase (enzyme "D") fits with substrate maltose, and maltose is a disaccharide (or specifically a sugar made of two glucose units).
# Answer:
If enzyme "D" is maltase, it fits with substrate **maltose**, which would be a **disaccharide (maltose)**.

### Question 4
# Brief Explanations:
The enzyme that acts on sucrose is sucrase. So if the substrate is sucrose, the enzyme "C" should be sucrase, and it fits with substrate sucrose.
# Answer:
If enzyme "C" is **sucrase**, it would fit with substrate **sucrose**, which is sucrose.

### Question 5
# Brief Explanations:
Lipase is an enzyme that acts on lipids (fats/oils). A common lipid substrate for lipase could be a triglyceride (which is a type of lipid made of glycerol and fatty acids). So lipase (enzyme "D") fits with a lipid substrate like a triglyceride, and the substrate is a lipid (triglyceride) and is the **substrate for lipase**.
# Answer:
If enzyme "D" is lipase, it would fit with **a triglyceride (or lipid)** , which is a lipid and is the **substrate for lipase**.

### Question 6
# Brief Explanations:
Peptidase is an enzyme that acts on peptide substrates. So if enzyme "E" is peptidase, it fits with a peptide substrate. The first blank is likely "enzyme" (to refer to enzyme "E").
# Answer:
If **enzyme** "E" is peptidase, it would fit with **a peptide** , the substrate, which is a peptide.

### Question 7
# Brief Explanations:
Lactase is the enzyme that specifically acts on lactose. So if enzyme "K" is lactase, it will fit substrate lactose (the blank here is likely to be filled with "lactose" or a notation, but based on the sentence, it should be "lactose" as the substrate). Wait, the sentence says "it will fit substrate ______ a lactose" – probably a typo, and it should be "it will fit substrate lactose" (or "it will fit substrate (lactose)"). So the blank is for "lactose".
# Answer:
If enzyme "K" is a lactase, it will fit substrate **lactose** (a lactose – correcting the sentence structure, the substrate is lactose).

### Question 8
# Brief Explanations:
Enzymes are specific (exhibit specificity) – they have a specific active site that only fits their specific substrate. So all enzymes are **specific** and will not fit any other molecule.
# Answer:
All the enzymes are **specific** and will not fit any other molecule.

### Question 9
# Brief Explanations:
When water is added to begin enzyme - catalyzed reactions (especially in hydrolysis reactions, where large molecules are broken down), this process is called **hydrolysis**. For example, in the breakdown of carbohydrates, proteins, or lipids, water is used to break the bonds, and this reaction is hydrolysis.
# Answer:
To begin enzyme action, water is added and is called **hydrolysis**.

### Question 10
# Brief Explanations:
When an enzyme and its substrate bind together, the complex formed is called an **enzyme - substrate** complex. This is a key concept in enzyme kinetics, where the enzyme (E) and substrate (S) form an ES complex before the reaction proceeds to form products.
# Answer:
An enzyme, joined with a substrate is called an **enzyme - substrate** complex.

### Question 11
# Brief Explanations:
Enzymes (especially human enzymes) work best at body **temperature (37°C)** and are not **consumed** in a reaction (enzymes are catalysts, they speed up reactions but are not used up in the process).
# Answer:
Enzymes work best at body **temperature (37°C)** and are not **consumed** in a reaction.
