Study Notes
Cellular Work Types
- Three types of cellular work driven by ATP:
- Chemical work: Synthesis of large molecules, e.g., proteins
- Mechanical work: Muscle contractions
- Transport work: Movement of solutes like ions across membranes
ATP Overview
- ATP (adenosine triphosphate) is the primary energy currency of cells
- Continuously recycled within cells to provide energy for various functions
- ATP is converted to ADP (adenosine diphosphate) by the removal of a phosphate group
Photosynthesis and Cellular Respiration
- Two main types of the reactions:
- Heat reactions: Energy release without useful work
- Light reactions (related to photosynthesis): Energy conversion from sunlight
Photosynthesis Equation
- Photosynthesis is summarized by the equation:
- 6CO2 + 6H2O → C6H12O6 + 6O2
- Shows the conversion of carbon dioxide and water into glucose and oxygen using light energy
Cellular Respiration Equation
- Cellular respiration can be represented by the equation:
- C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
- Illustrates how glucose and oxygen are used to produce carbon dioxide, water, and ATP as energy
Energy Transformation
- ATP is critical in transforming energy from food into usable energy for cellular processes
- Continuous cycle of ATP production and conversion maintains cellular function and energy supply
