AP Biology - Cell Structure, Function, and Endosymbiosis

Flashcards covering primary endosymbiosis, eukaryotic organelle functions, and cellular compartmentalization based on AP Classroom practice questions.

Model of Primary Endosymbiosis

A process where a free-living prokaryotic cell is engulfed by a larger cell; supported by the fact that the resulting organelle has a double membrane.

Golgi Apparatus

The organelle that acts as the site of modification and packaging of proteins and lipids prior to export from the cell.

Mitochondrion

The organelle that is a major producer of ATP and is found in both heterotrophs and autotrophs.

Eukaryotic Compartmentalization

An evolutionary advantage in eukaryotic organisms where organelles compartmentalize cellular processes, thereby increasing the efficiency of those processes.

Advantage of Internal Membranes

Internal membranes isolate specific reactions and contribute to cell function by providing a favorable local environment for metabolic reactions, increasing metabolic efficiency.
