Lipids, Membranes, Cells and Transport

A set of flashcards covering essential vocabulary and concepts related to lipids, cell membranes, and organelles as discussed in the lecture.

Lipids

Large and varied group of non-polar molecules that are insoluble in water but dissolve easily in organic solvents.

Triglycerides

Made of 3 fatty acids combined with 1 molecule of glycerol.

Saturated Fatty Acids

Fatty acids with no double bonds between carbon atoms.

Mono-unsaturated Fatty Acids

Fatty acids with one double bond between certain carbon atoms.

Poly-unsaturated Fatty Acids

Fatty acids with more than one double bond between certain carbon atoms.

Plasma Membrane

A membrane that surrounds the cell, selectively permeable to control substance transport.

Nucleus

Contains genetic material (DNA) and is responsible for controlling cell activities.

Mitochondrion

An organelle responsible for producing ATP through aerobic respiration.

Rough Endoplasmic Reticulum

A series of membranes studded with ribosomes for protein synthesis and transport.

Golgi Apparatus

Modifies, sorts, and packages proteins for secretion or delivery to other organelles.

Compartmentalization

The process of separating different reactions and concentrations within the cell.
