Question 1 of 4
Which biological macromolecules function primarily as biological catalysts by lowering activation energy?
Explanation: Enzymes are specialized proteins that catalyze metabolic reactions by significantly lowering the activation energy required.
Question 2 of 4
What is the primary role of the electron transport chain in cellular respiration?
Explanation: The electron transport chain uses high-energy electrons to create a proton gradient that drives ATP synthesis through oxidative phosphorylation.
Question 3 of 4
Which genetic principle is demonstrated when heterozygous individuals express a phenotype that is an intermediate blend of two alleles?
Explanation: Incomplete dominance occurs when neither allele is completely dominant, resulting in a blended intermediate phenotype.
Question 4 of 4
What physiological mechanism acts as the primary control system to maintain internal homeostatic balance?
Explanation: Negative feedback loops counteract deviations from a set point, effectively stabilizing internal physiological variables.
