Question
Answer
What's the difference between "fit" and "healthy"? Can you be one without the other?   show
🗑
What is "areobic respiration"?   show
🗑
show Glucose + Oxygen = Carbon Dioxide + Water (+ Water)  
🗑
show C6H12O6 + 6O2 = 6CO2 + 6H2O (+ energy)  
🗑
show After vigorous exercise, your muscles are still short of oxygen. You also need the extra oxygen to break down the lactic acid in the muscles. The less fit you are, the higher the oxygen debt.  
🗑
Name 6 nutrients the body needs and what they are needed for.   show
🗑
show This is where someone is 20% (or more) over the recommended body weight.  
🗑
Name 3 disorders/diseases that obese people are more likely to get.   show
🗑
show Anorexia or Bulimia.  
🗑
Name three types of digestive enzyme and say what they do.   show
🗑
How does bile help digestion?   show
🗑
show Fungi - can cause atheletes foot. Bacteria - can cause cholera. Viruses - Flu is caused by a virus. Protozoa - dysentry is caused by protozoa.  
🗑
Explain how the immune system deals with pathogens.   show
🗑
Explain how immunisation stops you from getting infections.   show
🗑
show Benign is where the tumour grows until there is no more room, these cells stay where they are and is the least dangerous of the two. Malignant is where the tumour can spread to other sites in the body. This is the most dangerous of the two.  
🗑
What is a double blind clinical trial?   show
🗑
show Prescription - you can buy them over the counter at a chemists. Addiction - they have a physical need for the drug. Tolerence - the body gets used to the drug. Rehabilitation - this a place to get help and support to overcome a drug addiction.

🗑
Describe the structure of DNA. What are genes?   show
🗑
show The order of the bases in a gene controls the order of amino acids in a protein.  
🗑
show Gamete formation - making sperm cells and egg cells, then fertilisation - the gametes join together. Mutations - changes in the genetic codes.  
🗑
Name three things that can cause genetic mutations.   show
🗑
show An allele is a different version of the same gene.  
🗑
