Admin Tonoplast membrane, ATPase, transporters, asstorage organelle. The tonoplast membrane, also called the vacuolar membrane, is a selectively permeable phospholipid bilayer that surrounds the vacuole in plant cells, fungi, and some protists. It acts as a gatekeeper, regulating the transport of ions, nutrients, and waste products between the cytoplasm and the vacuole. The tonoplast plays a … Read more

Biogenesis of Mitochondria Mitochondria are essential organelles responsible for cellular respiration and energy production. They primarily arise through the growth and division of pre-existing mitochondria or from promitochondria. Microscopic evidence strongly supports this theory. Observations under a phase-contrast microscope have revealed mitochondria in the process of dividing. Additionally, electron microscopy studies on green algae Micromonas—which … Read more
Mitochondrial DNA and Protein Synthesis 1. Role of mtDNA Mitochondrial DNA (mtDNA) codes for ribosomal RNAs, transfer RNAs (tRNAs), and small mitochondrial polypeptides. Several pieces of evidence support the conclusion that mtDNA serves as a template for the transcription of mitochondrial RNAs (mtRNAs): 2. Ribosomes Mitochondrial ribosomes differ from cytoplasmic ribosomes in size and chemical … Read more
Mitochondrial DNA Replication Mitochondrial DNA (mtDNA) replication is a unique process distinct from nuclear DNA replication. Unlike nuclear DNA, which replicates in the S-phase of the cell cycle, mtDNA replicates independently throughout the cell cycle. Features of mtDNA Replication Steps of Mitochondrial DNA Replication Enzymes Involved in mtDNA Replication Enzyme Function DNA Polymerase γ (POLG) … Read more
