Introduction to Proteins and Their Functions in Molecular and Cell Biology

Flashcards covering the central role and key functional categories of proteins within cellular biology based on Chapter 1-4 lecture notes.

MDs CATs

A mnemonic used to remember six major functions that proteins play in cells: Movement, Defense, Structure, Catalysis, Transport, and Signaling.

Euglena

A single-celled organism that utilizes a protein-built flagella to swim through water.

Antibodies

Proteins produced in response to an infection or vaccine that allow cells to fight off invading pathogens.

Cas9

A bacterial protein that defends bacteria against invading double-stranded DNA viruses by recognizing and chopping up the viral DNA.

Cytoskeleton

An internal cell structural network made entirely of proteins, including microtubules, actin, and intermediate filaments.

Enzyme
