C6H1206 + 6O2 ---> 6CO2 + 6H20 1 of 36 What are different forms of genes called? Alleles 2 of 36 What are Mitochondria? Structures in the cytoplasm where energy is released during Photosynthesis 3 of 36 What is the equation for Aerobic respiration and where does it occur? Glucose + Oxygen ---> Carbon dioxide + Water, occurs in the Mitochondria 4 of 36 What are Enzymes? Protein molecules made up of long chains of amino acids, folded to form active sights, where the Substrate of the reaction binds with the Enzyme 5 of 36 What is a Gene? A small section of DNA which codes for a particular combination of amino acids which makes a specific protein 6 of 36 What is Huntingdon's disease caused by? A dominant allele inherited from one parent 7 of 36 During photosynthesis, by what and where is light absorbed? Absorbed by the chlorophyll in the chloroplasts 8 of 36 What are the limiting factors of photosynthesis? Light, Temperature, Carbon Dioxide levels 9 of 36 What do Enzymes control? Chemical reactions inside the cell 10 of 36 What is an example of a specialised cell? Root hair cell 11 of 36 What is Diffusion? The movement of particles from an area of high concentration, to and area of low concentration 12 of 36 What is Osmosis? Diffusion of water from a dilute solution to a concentrated solution through a partially permeable membrane 13 of 36 Nucleus Controls all cell activity and contains instructions for making new cells 14 of 36 What is Cystic Fibrosis caused by? A recessive allele inherited from both parents 15 of 36 What is the equation for Photosynthesis? Carbon Dioxide + Water ---> Glucose + Oxygen 16 of 36 What is the symbol equation for Photosynthesis? 6CO2 + 6H20 ---> C6H1206 + 602 17 of 36 How are Gametes formed from body cells? Meiosis 18 of 36 What other structures are found in plant cells but not in animal cells? Cell Wall, Chloroplasts, Permanent Vacuole 19 of 36 Ribosomes Where protein synthesis takes place 20 of 36 Cell Membrane Controls the passage of substances in and out of the cell 21 of 36 What core temperature is best for Enzyme activity? 37"C 22 of 36 What is your body temperature controlled by? The Thermoregulatory centre in the brain 23 of 36 Where are your blood sugar levels controlled? The Pancreas 24 of 36 What hormones are involved in controlling the blood sugar levels and what do they convert? Insulin which converts glucose into glycogen, and Glucagon which converts glycogen into glucose 25 of 36 In diabetes, why may the blood sugar levels rise fatally high? The Pancreas does not secrete insulin 26 of 36 What factors affect Enzyme activity? Temperature, pH 27 of 36 What Enzymes can be found in biological detergents? Protease and Lipase 28 of 36 Describe the carbon cycle Carbon dioxide is removed from the atmosphere by photosynthesis, and replaced by combustion and respiration 29 of 36 Cytoplasm Liquid gel which chemical reactions need for life 30 of 36 Cell Wall Strengthens and supports cell 31 of 36 Chloroplasts Absorbs light energy for Photosynthesis 32 of 36 Permanent Vacuole Space filled with sap that keeps the cell rigid 33 of 36 How do body cells divide to produce more identical cells? Mitosis 34 of 36 What did Gregor Mendel suggest? Separately inherited factors which we now call genes 35 of 36 What do Enzymes in the Ribosomes do? Catalyse the build up of proteins from amino acids 36 of 36
