What happens in cells

• What happens to enzymes at low temperatures?

  enzyme reactions are slow. This is because there are less collisions between the enzyme and substrate
• What happens to the enzyme at high temperature?

  They speed up as the temperature rises until an optimum temperature is reached. After this point the reaction will slow down and eventually stop.
• enzyme and ph

  Most enzymes work fastest in neutral conditions. Making the solution more acid or alkaline will slow the reaction down.
• what is the lock and theory?

  The same way a key fits into the lock. The substrate Fits into the enzyme active-site. The enzyme Is the lock, and the substrate is the key.
• Structure of DNA

  Made up of 2 strands

  Double helix

  4 bases
• What does denatured mean?

  when the active-site changes shape. Enzymes become denatured at high temperatures, or when the enzyme reaches the optimum pH
