Chapter 6 - Protein Function Flashcards
Metabolic
Reaction catalysts that control metabolic influx
Actin
Cytoskeletal protein in animal cells, inside muscles
Tubulin
Roads for movement of organelles/chromosomes during cell division
Collagen
Structural protein in animals, connective tissue component
Passive Transport Protein
Energy independent, allows molecule movement across a membrane, chemical gradient
Active Transport Protein
Requires energy, pumps molecules/ions against a concentration gradient
Simple Diffusion
Molecules move directly through the membrane without interacting with other molecules
Facilitated Diffusion
Movement of molecules pass through the membrane using a carrier protein
Primary Active Transport
ATP hydrolysis drives conformational changes in the protein complex
Secondary Active Transport
Downhill electromagnetic gradient energy co-transports a molecule in an uphill gradient
Cell Signaling
Transmits extracellular signals by functioning as a molecular switch
Nuclear Receptor
Transcription binding factors regulate gene expression in ligand binding
Gene Caretaker
Maintains genetic information integrity and accessibility
Hemoglobin
Protein in blood cells, transports heme-bound O2 from the lungs to tissues
Myoglobin
Stores O2 in muscles for later use
Heme
Fe2+ porphyrin complex, binding O
