What unique feature of enzymes allows them to be highly specific for their substrates?
✔✔ The unique three-dimensional shape of an enzyme allows it to fit only specific substrates,
much like a key in a lock.
How does the structure of glycogen contribute to its function as an energy reserve?
✔✔ Glycogen's branched structure allows for rapid mobilization of glucose when energy is
needed quickly.
What is the significance of the term "denaturation" in protein chemistry?
✔✔ Denaturation refers to the process where proteins lose their functional shape due to
environmental changes, impacting their biological activity.
How do vitamins function as coenzymes in metabolic reactions?
✔✔ Vitamins often serve as coenzymes, assisting enzymes in catalyzing biochemical reactions
by providing essential functional groups.

, What role do hydrogen bonds play in the stability of the DNA double helix?
✔✔ Hydrogen bonds between complementary nitrogenous bases stabilize the DNA double helix
structure, allowing for accurate replication.
How do protein interactions influence cellular signaling pathways?
✔✔ Protein interactions can activate or inhibit signaling pathways, leading to a cascade of
cellular responses based on specific stimuli.
What is the impact of enzyme concentration on the rate of a biochemical reaction?
✔✔ Increasing enzyme concentration typically increases the reaction rate until substrate
availability becomes the limiting factor.
How does substrate concentration affect enzyme kinetics according to the saturation concept?
✔✔ As substrate concentration increases, the reaction rate rises until it reaches a maximum
velocity, where all active sites are occupied.
What differentiates competitive inhibition from non-competitive inhibition in enzyme activity?
