Study Notes
Respiration
- A vital process for all organisms
- Occurs continuously throughout life
- Involves breaking down glucose for energy
- Requires oxygen
Chemical Reaction of Respiration
- $C_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O + energy$
- Occurs inside living cells (tissue)
- Glucose breakdown happens in a series of steps
- Some steps occur in the cytoplasm, others in the mitochondria
- Each step of the breakdown is catalyzed by a specific enzyme
- Energy released during glucose breakdown is not all heat, a majority is converted to ATP (Adenosine Triphosphate)
- One mole of glucose produces 38 molecules of ATP
- ATP acts as the "energy currency" within a cell
Animals Need More Energy than Plants
- Animals need more energy than plants for physical activities
- Birds and mammals also need energy to regulate body temperature
Glucose and Respiration
- Simple carbohydrates provide the main energy source for cellular functions
- If carbohydrates are not available, proteins and fats are broken down for energy
- Animals that rely on proteins for food have extra amino acids that convert to Urea through digestion
- Glucose can be used immediately or stored as glycogen for future energy demands
Energy Use by Body cells
- Synthesis of proteins from amino acids
- Production of enzymes
- Muscle contraction
- Nerve impulse conduction
- New cell production
- Maintaining body temperature (primarily for warm-blooded animals)
