Question

Choose any two mitochondrial matrix constituents.

Answer 1

Mitochondria:

1. Mitochondrion (mitochondria) is a membrane-bound structure found in eukaryotic cells.
2. The word mitochondrion has Greek roots, mitos, "thread", and chondrion, "granule".
3. This organelle is a "cellular power plant" because it generates cellular energy (ATP), which is used as a source of chemical energy.

Matrix of Mitochondria:

1. An outer membrane, an inner membrane, and a gel-like material called the matrix to make up the mitochondrion.
2. This space is relatively viscous compared to aqueous cytoplasm.
3. The mitochondrial matrix consists of mitochondrial DNA, ribosomes, soluble enzymes, small organic molecules, nucleotide cofactors, and inorganic ions.
4. Enzymes in the matrix facilitate reactions responsible for the production of ATP, such as the citric acid cycle, oxidative phosphorylation, oxidation of pyruvate, and beta-oxidation of fatty acids.
