Which of the following is the storage polysaccharide in animals?
Starch
Cellulose
Chitin
Glycogen
Chitin is a polysaccharide found in:
Plant cell walls
Animal liver
Bacterial cell walls
Exoskeleton of insects
Which of the following is NOT a characteristic of metabolic pathways?
Regulation of the pathway
Catalysis by enzymes
Occurring in a non-sequential manner
Often compartmentalized within cells
The process of converting complex molecules into simpler ones with the release of energy is known as:
Anabolism
Catabolism
Metabolism
Homeostasis
Which of these is a primary function of ATP in metabolism?
Enzyme synthesis
Genetic coding
Structural support
Energy transfer
Enzymes play a crucial role in metabolism by:
Providing energy for reactions
Consuming energy to halt reactions
Lowering the activation energy of reactions
Altering the equilibrium constant of reactions
Metabolic pathways are often regulated through feedback inhibition. This means:
The substrate of a pathway stimulates the first enzyme.
Enzymes are constantly synthesized regardless of product concentration.
The end product of a pathway inhibits an earlier enzyme in the pathway.
Enzymes are degraded rapidly after catalyzing a reaction.
Which of the following is an example of an anabolic process?
Breakdown of glucose into pyruvate
Protein synthesis from amino acids
Hydrolysis of starch into glucose
Oxidation of fatty acids
The active site of an enzyme is:
The entire enzyme molecule.
The region where the substrate binds.
A non-protein component.
An inhibitor binding site.
