Question

enzymes: temperature
fill in the gaps to describe how increasing temperature affects enzyme function
increasing temperature up to the optimal temp
increasing the temperature raises the ____ energy, so the molecules move __. this makes the enzymes more likely to __ with the __ molecules. the collisions that happen are also more likely to result in a successful ____.
increasing temperature above the optimal temp
however, if the temperature gets too far above the ____ temperature of the enzyme, it can break some of the __ that hold the enzyme in its shape, causing it to __. this means the enzyme will no longer work as a ____
we can experiment to find the optimal temperature of an enzyme.
lets take a look at two enzymes from different organisms

Explanation:

• When temperature increases up to the optimal temp:
• Temperature affects kinetic energy. Higher temp means higher kinetic energy.
• Molecules move faster with more kinetic energy.
• Enzymes collide with substrate molecules.
• Successful collisions lead to reactions.
• When temperature is above the optimal temp:
• Optimal temperature is crucial for enzyme structure.
• Bonds (like hydrogen bonds in protein structure) can break.
• Enzyme denatures (loses shape).
• Denatured enzyme can't act as a catalyst.

Answer:

• Increasing temperature up to the optimal temp:
• kinetic
• faster
• collide
• substrate
• reaction
• Increasing temperature above the optimal temp:
• optimal
• bonds
• denature
• catalyst
