Mitochondria are often considered the powerhouses of the cell since they are the organelles responsible for the generation of ATP, the energy currency of the cell.. Mitochondria are comprised of an outer and an inner membrane. [II] Associated granules: Cristae are sub-compartments of the inner membrane of mitochondria and are essential to mitochondrial function. Explanation: No explanation available. Correct Answer: mitochondria. ... proteins associated with DNA in the nucleus. The site for ribosomal RNA synthesis is the. The cristae possess F 1 particles and the coupling factors. Further more the activities of several enzymes, (i.e., succinate dehydrogenase, β-hydroxy buty rate dehydrogenase, rotenone sensitive NADH- cytochrome-C-reductase and ATPase) predominate in the cristae. Mitochondrial membrane potential (ΔΨ m) is the main driving force for ATP synthesis at the folds of the inner mitochondrial membrane, the cristae.Measurement of ΔΨ m in individual cristae reveals that crista junctions provide electrical insulation and sustain polarization of individual mitochondrial cristae within a single mitochondrion even when neighbouring cristae are damaged. Majority of the biochemical reactions of the mitochondrion occur associated with cristae. When there is a greater surface, the efficiency of ATP production increases. UP CPMT 2007: Cristae are associated with which of the following ? (A) Cytoplasm (B) Mitochondria (C) Protoplasm (D) Endoplasmic reticulum. Cristae Definition. This thinning of the IMM facilitates its curvature where the two monomers are associated at the apices of the mitochondrial cristae. In addition to measures of width at the cristae junctions, a functional parameter is also attributed to the space within cristae, known as the cristae lumen. Be the first to write the explanation for this question by commenting below. ... is becoming very clear that the role of cristae morphology has deep implications for human health as perturbations in cristae structure are associated with a wide array of pathologies. Interestingly, 3D tomography showed some COX-positive lamellar cristae were not connected to IBM. on the surface of rough endoplasmic reticulum. What are Cisternae? Options (a) mitochondria (b) cytoplasm (c) protoplasm (d) endoplasmic reticulum. We found that the formation of lamellar cristae was associated with the gain of cytochrome c oxidase (COX) function, and the COX subunit, COX4, was localized predominantly to organized lamellar cristae. The cristae junctions represent the opening of the cristae, whereby the width is a measure of the distance between two opposing regions of intersection between the cristae and IBM. Cristae are loaded with ATP synthases and variety of cytochromes. Could this allow us to detect pathological changes in cristae architecture associated with disease at any earlier stage? A key question in mitochondrial biology concerns the release of mitochondrial DNA. Cristae are associated with which of the following? Check Answ nucleolus. Which cytoskeletal element is NOT correctly associated with its characteristic? Thus, cristae are necessary to increase ATP production in a cell. A. stroma, cristae B. photosynthesis, mitochondria C. thylakoid membranes, matrix D. protein synthesis, lysosomes. Which organelle contains cristae where enzymes and electron carriers for aerobic respiration are found? Cristae in mitochondria are individual batteries that maintain different membrane potentials that can affect energy production and ROS signaling. Does looking at the mean ΔΨm using traditional methods provide a representative image of the mitochondrial health of the cell? A.
