Study Notes
Cell Structure and Function
- Cell membrane regulates the movement of materials into and out of the cell
- Nucleus stores DNA and regulates cell functions
- Mitochondria is the site of cell respiration, producing ATP
- Ribosome synthesizes proteins by translating mRNA into a specific amino acid sequence
Cellular Respiration
- Energy stored in carbohydrates is released as ATP through the process of respiration
- Mitochondria is responsible for cell respiration, producing ATP
Oxygen and Carbon Dioxide Cycling
- Photosynthesis and respiration are the processes that cycle oxygen and carbon dioxide through ecosystems
- Concentrations of oxygen and carbon dioxide fluctuate throughout the day in aquatic ecosystems
Homeostasis
- Feedback mechanisms are used by the body to maintain homeostasis
- Insulin, released by the pancreas, lowers blood sugar levels back to normal
Immunity and Vaccines
- Vaccines contain dead or weakened pathogens that stimulate the immune system to produce antibodies
- Antibodies can be produced in the future to prevent infections and develop immunity
