- Bioenergetics
- Metabolism - chemical reactions
- SUM OF THEM ALL!!!
- Metabolism - chemical reactions
- Glucose
- Amino Acids
- Starch
- Roots
- Stems
- Leaves
- Stems
- Insoluble
- Cell doesn't swell up with water
- Roots
- Chlorophyll
- Pigment
- Absorbs light
- Photosynthesis
- Endothermic
- LIMITING FACTORS
- Light
- night
- Light
- Green plant cells
- Carbon Dioxide + Water ----> Glucose + Oxygen
- 6(carbon_dioxide) + 6(water) ------> glucose + 6(oxygen)
- glucose ---- c(6)h(12)o(6)
- 6(carbon_dioxide) + 6(water) ------> glucose + 6(oxygen)
- (Chlorophyll)
- Disease
- LIMITING FACTORS
- Light
- night
- Light
- Environmental Stress
- Lack of nutrients
- (Chlorophyll)
- Disease
- Damaged chloroplasts
- a.u. = arbitrary units
- Shades + ventilation in the summer
- Enclosed environment
- Pests
- Respiration
- Exothermic
- Energy transfer via. breakdown of glucose (sugar)
- Muscle contraction
- BUILDING of larger molecules (e.g. proteins)
- Maintaining body temperature (mammals + birds)
- GLUCOSE
- Starch (plant, storage)
- Glycogen (animal, storage)
- Glycerol
- 3 fatty acids
- LIPIDS
- LIPIDS
- 3 fatty acids
- AMINO ACIDS
- Proteins
- Glucose
- Nitrate ions
- Glucose
- everything!
- EXCESS protein
- Urea
- excreted in urine
- Urea
- AEROBIC Respiration
- Involves oxygen
- Most reactions: occur in mitochondria
- Involves oxygen
- ANAEROBIC Respiration
- Produces lactic acid
- Usually occurs in muscle cells
- ANAEROBIC RESPIRATION IN PLANTS + YEAST
- Yeast = fermentation
- Bread
- Carbon Dioxide
- Makes bread rise
- Carbon Dioxide
- Bread
- Yeast = fermentation
- c6h12o6 ------> c2h6o + co2
- Glucose ----> Ethanol + Carbon Dioxide
- ANAEROBIC RESPIRATION IN PLANTS + YEAST
- Yeast = fermentation
- Bread
- Carbon Dioxide
- Makes bread rise
- Carbon Dioxide
- Bread
- Yeast = fermentation
- ANAEROBIC RESPIRATION IN PLANTS + YEAST
- Glucose ----> Ethanol + Carbon Dioxide
- Exercise
- What increases?
- Heart rate
- Breathing rate
- Muscle fatigue
- Muscles contract less efficiently
- Oxygen debt
- Lungs, heart blood
- Has to compensate, by reacting with any lactic acid
- Pulse + breathing rate stay elevated
- Lactic acid may be transported to liver
- Converted to glucose
- by blood
- What increases?
