Study Notes
Spelling and Definitions
- The correct spelling for a person who treats dental issues is "dentist."
- "Dentist" commonly experiences misspellings, often miswritten as "dentist."
- Accurate spelling related to tooth care is essential for professionalism.
Molecular Transport Processes
- Passive transport does not require energy or carriers for the movement of molecules across cell membranes.
- Small nonpolar molecules, such as oxygen and carbon dioxide, can move through double phospholipid layers via simple diffusion.
- The concentration gradient significantly affects the rate of diffusion for ions across cell membranes.
- Membrane permeability, influenced by factors like temperature and lipid composition, increases diffusion rates for substances.
Types of Transport Mechanisms
- Endocytosis involves large substances entering a cell by engulfment in a vesicle.
- Active transport requires energy to move substances against their concentration gradient.
- Facilitated diffusion requires a carrier protein but does not need energy to occur.
- Primary active transport differs from secondary active transport in that it directly uses ATP for energy, while secondary active transport relies on the gradient created by primary transport.
Bulk Transport and Homeostasis
- Bulk transport involves the endocytosis of molecules from outside to inside the cell.
- Effectors play a critical role in a homeostatic system by carrying out responses to changes detected by sensors.
- The nervous system communicates through nerve impulses, facilitating rapid responses to stimuli.
Temperature Regulation and Diffusion
- Thermoreceptors in skin and core body regions sense changes in temperature during body temperature regulation.
- The type of transport that moves substances against an electrochemical gradient is classified as active transport.
- Facilitated diffusion requires specific carrier proteins for transport but not ATP energy.
Cellular Processes
- "Cell drinking" refers to pinocytosis, a process by which cells intake liquid substances.
- Exocytosis involves movement of macromolecules enclosed in membrane-bound vesicles out of the cell.
