Biochemistry

• What is the organization equation?

  cells - tissues - organs - organ system - organism
• What is the body system equation?

  nerve cell - muscle tissue - heart, blood - circulatory system - human
• Name the body parts

  Bronchus, bronchiole, alveolus, intercoastal, rib, diaphragm, lung, heart, ribcage, trachea
• Where does gas exchange take place?


  alveoli and blood vessel
• What happens in respiration?

  Fresh air inhaled - oxygen - diffuses from alveoli - capillary

  
  

  Exhale - carbon dioxide - diffuses capillary - alveoli
• What is an alveoli?

  thin, circular, large surface area , one cell thick, thin diffusion
• What is the equation for aerobic respiration?

  glucose + oxygen - carbon dioxide + water + energy
• What happens in the small intestine?

  carbohydrates digested - glucose - small intestine - blood stream - cells - mitochondria for respiration
• What happens with oxygen?

  Inhale lungs - Diffuses into alveoli - red blood cells binds with red piment - oxygen released into cells - mitochondria uses for respiration
• What do we use energy for?

  movement, warmth, growth, repair
• What does exercise do?

  more movement - more energy required for muscle contractions - rate of respiration increases
• What is heart rate?

  number of time our heart beats per minute
• What is breathing?


  inhaling and exhaling use lungs, ribs, diaphragm
• What is respiration?


  a chemical reaction in cells, uses oxygen, glucose
• What is the equation for anerobic respiration?

  glucose - lactic acid + energy
• What is anerobic respiration?

  gives lactic acid, fills up muscle cells, stops them working, gives fatigue, only small amount of energy
• What equation do you use to get rid of lactic acid?

  lactic acid + oxygen - carbon dioxide + water
• What is the fermentation equation?

  glucose - carbon dioxide + alcohol +energy
• What is an example of fermentation?

  bread dough, beer making
• What is the equation of photosynthesis?

  Water + carbon dioxide - (chlorophyll and light) - glucose + oxygen
• What is photosynthesis?


  light from the sun, oxygen from the air, nutrition from the soil, carbon dioxide released in the air, chlorophyll food for the plant
