Question

1. using the graph, what is the ph needed for maximum enzyme effectiveness? 5 ph
2. using the graph, what will happen to the enzymes effectiveness if the solution is made very acidic?

a). why

1. fill in the table below regarding the four main groups of molecules discussed in class.

all molecules

	carbohydrate	lipid	protein	nucleic acid
polymer	disaccharides polysaccharides	fats	protein	dna rna

Explanation:

Step1: Analyze the enzyme - effectiveness graph for question 21

Find the peak of the curve on the graph. The x - axis represents pH and the y - axis represents the rate of reaction (enzyme effectiveness). The peak occurs at pH = 5.

Step2: Analyze the effect of acidity on enzyme effectiveness for question 22

Enzymes have an optimal pH range for activity. Very acidic conditions can denature enzymes. When the solution is made very acidic (low pH), the enzyme's effectiveness will decrease. This is because the low pH can disrupt the hydrogen bonds and other non - covalent interactions that maintain the enzyme's three - dimensional structure.

Step3: Fill in the table for question 23

• Carbohydrates: Monomer is monosaccharides and polymers are disaccharides and polysaccharides.
• Lipids: Monomer is fatty acids and glycerol (it seems 'katty acids' is a misspelling of fatty acids), and polymers are triglycerides (it seems 'lipids' in the polymer column is a bit too general, triglycerides are a common type of lipid polymer).
• Proteins: Monomer is amino acids and polymer is protein (more precisely, polypeptides which fold into proteins).
• Nucleic Acids: Monomer is nucleotides and polymer is DNA and RNA.

Answer:

1. 5
2. The enzyme's effectiveness will decrease. Because low pH can denature the enzyme by disrupting non - covalent bonds in its structure.
