1. What is true of a competitive inhibitor? A. It has the same mass as the substrate. B. It has a structure similar to the substrate. C. It forms the same products as the substrate. 2. The active site of an enzyme E, which catalyzes a reaction X, is partially following quantities associated with X is most likely to be affected by th E compared to the native form of E? A. the constant k_(b) B. the heat of reaction Delta H C. the rate-constant k D. the equilibrium constant k_(eq) 3. Which of the following enzyme types catalyzes the formation of a single b substrates? A. Ligase B - Oxidoreductase C. Isomerase D. Hydrolase 4. Enzymes undergo a decrease in efficiency in the presence of exces regain this efficiency once temperature returns to normal this suggests that does not disrupt which of the following aspects of enzyme structure? A. Peptide bonds B. Van der Waal's forces C. Hydrophobic interactions D. Hydrogen bonds 5. Local conditions can affect the specificity of an enzyme for its substrate, and catalytic ability :which of the alterations would most likely not affe manner? A. Increased temperature Increased concentration of H+ Increased substrate concentration Increased concentration of salts Pancreatic amylase is a digestive enzyme found in the small intestine. It helps starch molecules later in the digestive process . Pancreatic amylase is unable to Lipids are too hydrophobic to be broken down by enzymes. Lipids are too small to bind to enzymes. Enzymes bind only to their specific substrates. Enzymes denature in the presence of lipids. hich of the following molecules cannot be classified as an enzymatic cofactor? line AD (Flavine adenine Dinucleotide) Variant 2
