A-Level Sciences

What’s inside

• In an A-Level Biology investigation, why is a control variable kept constant?
• Which process produces ATP directly by transferring a phosphate group from an intermediate molecule to ADP?
• Why does increasing temperature eventually reduce the rate of an enzyme-controlled reaction?
• In A-Level Physics, what does the gradient of a velocity–time graph represent?
• Match each biological molecule to its principal structural feature.
• Match each chemical quantity or term to its correct description.
• Match each physics quantity to its SI unit.
• Match each A-Level practical technique to its main purpose.
