Practice C1.1 Enzymes and metabolism with authentic IB Biology exam questions for both SL and HL students. This question bank mirrors Paper 1A, 1B, 2 structure, covering key topics like cell biology, genetics, and ecology. Get instant solutions, detailed explanations, and build exam confidence with questions in the style of IB examiners.
Which graph pattern best represents the effect of increasing substrate concentration on enzyme activity?
In an experiment measuring enzyme activity, which of the following would best indicate the reaction rate?
According to the induced fit model, which of the following occur?
I. The enzyme changes shape slightly to better fit the substrate
II. The active site becomes rigid and locked
III. The enzyme-substrate complex stabilizes the transition state
Which of the following best explains why enzymes are specific?
Which of the following explains why enzyme specificity is important in metabolism?
A student investigates catalase breaking down hydrogen peroxide into water and oxygen. Which sequence correctly describes the experimental process?
What is the benefit of enzymes in cellular reactions?
Some bacteria can synthesize the amino acid isoleucine from threonine, a process involving five enzymes ( to ) and four intermediary products (P, Q, R and S). The production of isoleucine is controlled by end-product inhibition.
Which statement describes this end-product inhibition?
In a catalysed reaction, which condition would most likely increase the rate of enzyme-substrate collisions?
How does high fever disrupt enzyme function at the molecular level?
