Organelles that generate energy through aerobic respiration.

Process used by mitochondria that converts glucose and oxygen into energy.

A series of chemical reactions in mitochondria that produce energy carriers.

Final stage of aerobic respiration that generates the majority of ATP.

Found in plant and animal cells, but not in bacteria.

Number of mitochondria varies by cell’s energy needs, e.g., liver cells have 500-1000.

Mitochondria are about 0.5-1 µm in diameter and 1-2 µm in length.

Mitochondria can change shape and move to areas requiring energy.

The semifluid environment inside mitochondria, containing enzymes for ATP production and mitochondrial DNA.

A net-like structure originating from the nuclear membrane, involved in protein and lipid synthesis, and modification.

A type of endoplasmic reticulum with ribosomes, involved in protein synthesis and modification.

A type of ER without ribosomes, synthesizes lipids and steroid hormones, and regulates calcium ions.

Double membraned organelle involved in photosynthesis.

Cell organelle that houses genetic material.

The outer layer that encloses the organelle.

Space between the outer and inner membranes.

Membrane that is selectively permeable, maintains proton gradient.

Folds of the inner membrane increasing surface area for reactions.

Process in the inner membrane generating ATP.

Proteins regulating material movement in and out of mitochondria.

A network of membranes studded with ribosomes for protein synthesis.

Includes protein folding, assembly, disulphide bond formation, glycosylation, and degradation of misfolded proteins.

A membrane structure that modifies proteins and lipids received from the RER.

The Golgi has distinct cis (receiving) and trans (shipping) faces.

Involves replacing sugar groups and modifying phospholipids.

Membrane-bound organelles containing hydrolytic enzymes for breakdown tasks.

Crucial for glycosylation and directing proteins, preventing cell death without it.

A network of fibrous proteins that maintain cell shape and facilitate movement.
