- BL5
- Limiting factors
- Factors include: Temperature, Light intensity and CO2 levels(All control speed of photosynthesis
- Mineral Ions:
- Nitrate causes growth but if there is a deficiency, Stunted Growth
- Potassium helps enzymes and respiration but deficiency means poor flower growth
- Phosphate creates DNA and respiration but deficiency means poor root growth
- Magnesium creates chlorophyll but if deficiency leaves turn yellow and can't photosynthesise
- To increase rates: Extra CO2, High temperature all in greenhouses
- Mineral Ions:
- Factors include: Temperature, Light intensity and CO2 levels(All control speed of photosynthesis
- Respiration
- Respiration takes place in cells and then mitochondria
- Creating energy using glucose, exothermic reaction as it is released
- Aerobic Respiration (Release of oxygen)
- Anaerobic Respiration(Incomplete respiration)
- Less energy is released and creates lactic acid is created and causes muscle fatigue or cramps
- Use of released energy: Muscle Contraction, Control body temperature and cell division
- Exercise
- Effects of exercise: Increased heart rate and breathing rate
- How to get rid of lactic acid: Transports lactic acid to liver, converts to glucose and creates oxygen debt(Extra oxygen needed by body)
- Metabolic rate
- Metabolism: All chemical reactions in an organism and how quick they occur, controlled by reactions
- Reactions and where?
- Photosynthesis; in plants
- Pepsin(Digestion of protein); stomach
- Amylase(Digestion of starch);mouth,small intestine
- Lipase(Digestion of fat);Small Intestine
- Conversion of glucose to starch;Storage tissues of plants
- Limiting factors
- How to change metabolic rate:Exercise,Age,Gender and genetics
- Exercise will:Decrease fat store,increase energy use and builds muscle and metabolism
