What is activation energy?

  1. AThe heat released when a reaction finishes

4.Medium

Why does a very high temperature stop most enzymes from working?

  1. AThe enzyme moves too slowly to meet the substrate
  2. BHeat makes the enzyme divide into amino acids instantly
  3. CThe substrate turns into a different enzyme

  2. BThe mRNA is copied back into DNA
  3. CThe ribosome goes back to the start codon
  4. DTranslation ends and the protein is released
7.Hard

Kidney tubule cells move glucose from the filtrate back into the blood, even when there is less glucose in the filtrate than in the cells. What does this show?

  1. AGlucose is moved by osmosis
  2. BGlucose is moved by active transport
  3. CGlucose moves only down its gradient
  4. DGlucose is moved by simple diffusion
8.Hard

A point mutation changes a codon in the middle of a gene into a stop codon. What is the most likely effect?

  1. AA shortened protein that usually does not work
  2. BNo change, because stop codons are ignored
  3. CA protein with one different amino acid
  4. DA protein that is longer than normal
