• Are chemical reactions natrally slow or fast

  slow
• 2 reasons why we can't make cells even warmer to increase the rate of reaction

  Higher temperatures could damage cells, Higher temperature will speed up non use-full reactions
• Enzyme definition

  A special type of catalyst that's made up of living organisms
• Enzymes are large proteins made up of a long chain of

  Amino acids
• The active site of an enzyme must be what to substrate

  complementary
• what is the name of the model that fits perfectly into the substrate

  Lock and key model
• What is the name of the model where the active site changes shape to fit in

  The induced fit model
• 2 Main models of enzyme reaction

  Lock and key, induced fit model
• Catalyst definition

  A substance that increases the speed of a chemical reaction, without being changed or used up in the process
• Active site definition

  Part of an enzyme with a unique shape thats complementary to the substrates of the reaction
• 2 factors affecting enzyme reaction

  Temperature, PH
• PH definition

  Measure of acidity
• Optimum definition

  where the highest recording/activity is
• what affect does a extremely high PH have on enzymes

  Denatures them
• How can increasing temperatures cause enzymes to Denature

  Bonds start to break down, enzyme and active site start to loose shape, enzyme and active site no longer be complementary to the substrate
• What 3 nutrients do we need in large quantities

  proteins, lipids, carbohydrates
• Why do we need carbohydrates

  provide us with energy
• Fats and oils together are known as

  lipids
• Why do we need lipids

  provide energy for chemical reactions, to insulate us and regulate our body temperature
• Meats, fish and legumes contain lots of

  proteins
• cheese, nuts and avocadoes contain lots of

  lipids
• Potatoes, bread and pasta contain lots of

  carbohydrates
• What food group is most important for growth and producing new cells

  proteins
• Which mineral is important for strong bones

  Calcuim
• Which vitamin is good for good eyesight and healthy hair and skin

  Vitamin A
• What disease can be caused by a lack of vitamin C

  Scurvy
• Why do we need fibre

  to help food move through our intestines
• 3 main ways which we lose water from our body

  Breathing, sweating, urinating
• Biological molecules definition

  Molecules found in living organisms and are produced by cells
• Nutrients definition

  Are substances that are needed for growth, repair, metabolism
• What 2 places are carbohydrates broken down in

  Mouth and small intestine
• what 4 things are amino acids made from

  carbon, nitrogen, hydrogen, oxygen atoms
• what 3 things are lipids made from

  carbon, hydrogen, oxygen
• What are 3 biological molecules

  Carbohydrates, lipids, proteins
• Is glucose a monomer or polymer

  Monomer
• Monomer is

  Simple structure of thing
• Polymer is

  Complex/more advanced thing
• Is glycogen a monomer or polymer

  Polymer
• What are monomers joined together to form proteins called

  Amino acids
• Lipids are only broken down in the

  small intestine
