Mr 10 Viii Differences Betwixt Mitochondria In Addition To Peroxisome

Mitochondrion are self duplicating, semi autonomous, double membrane bound, cytoplasmic organelles institute inwards all eukaryotic cells. 

Peroxisomes are microbodies or self duplicating; unmarried membrane jump organelles present inwards all eukaryotic cells. They comprise oxidative enzymes, such every bit catalase together with urate oxidase, at such high concentrations.

Mitochondrion vs  Peroxisomes 

Mitochondrion	Peroxisomes
Double membrane jump organelle	Single membrane jump organelle
Semi-autonomous organelle, contains deoxyribonucleic acid called mt deoxyribonucleic acid or mitochondrial genome	No deoxyribonucleic acid
New mitochondrion arise yesteryear increment together with fission	New peroxisome likewise  arise yesteryear increment together with fission
Mitochondrial proteins are coded yesteryear both mitochondrial deoxyribonucleic acid together with Nuclear DNA	Peroxisomal proteins are encoded yesteryear nuclear DNA
Mitochondrial proteins are made on gratis cytoplasmic ribosomes together with ribosomes within mitochondrion	Peroxisomal proteins are made on gratis cytoplasmic ribosomes
Unfolded Proteins are post‐translationally imported alongside the assistance of proteins complexes called TIM, TOM together with OXA complex	Folded Proteins are post‐translationally imported alongside the assistance of proteins coded yesteryear PEX genes named peroxins
Import betoken sequence is called "mitochondria-targeting sequence" (MTS), which is located at the amino termini or north termini of the preproteins or unfolded protein	Import betoken is a  specific sequence of 3 amino acids located at the C terminus of many peroxisomal proteins
Signal sequences at north terminus are removed afterward import yesteryear a protease called betoken peptidase inwards the mitochondrial matrix.	Generally, Signal sequences are non removed afterward import
Function: Oxidative phosphorylation together with ATP synthesis which is used to stimulate diverse cellular activities. Matrix is the site of β oxidation	Functions: Involved many metabolic processes or oxidative reactions, such every bit β‐oxidation of real long‐chain obese acids releasing energy,  and synthesis of plasmalogen, an of import membrane factor inwards encephalon together with pump together with bile acids every bit good every bit generation together with degradation of hydrogen peroxide during detoxification.

TIM: Translocase Inner Membrane; TOM: Translocase Outer Membrane
