Cell Structure: Cytoplasm, Nucleus, and Extracellular Components

Vocabulary flashcards covering cytoplasm, nucleus, and extracellular components mentioned in the notes.

Cytoplasm

Intracellular fluid (ICF) containing organelles; the watery environment inside the cell; mainly water; site of glycolysis (glucose metabolism that produces ATP).

Intracellular fluid (ICF)

Fluid inside the cell; part of the cytoplasm.

Organelles

Specialized structures within the cytoplasm that perform specific cellular functions.

Glycolysis

The glucose metabolism process that produces ATP, occurring in the cytoplasm.

Nucleus

The organelle that controls cellular activity; the cell's command center.

Extracellular materials

Substances found outside the cell, including extracellular fluid, secretions, and extracellular matrix.

Extracellular fluid (ECF)

Fluid outside cells that contains nutrients, regulatory substances, and wastes; includes interstitial fluid, blood plasma, and cerebrospinal fluid.

Extracellular matrix

Substance secreted by cells, composed of proteins and polysaccharides, that self-assembles into an organized mesh to bind body cells together.

Cellular secretions

Including digestive secretions, and lubricating fluids.
