what is cristae? functions of cristae with example. which cell organelles this was present?
Answers
what is cristae?
Answer:A crista is a fold in the inner membrane of a mitochondrion. The name is from the Latin for crest or plume, and it gives the inner membrane its characteristic wrinkled shape, providing a large amount of surface area for chemical reactions to occur on.
Functions:
Before we can explain the functioning of the crista (plural = cristae), we need to revisit what a mitochondrion does. The mitochondrion is the cellular organelle where cellular respiration takes place. Cellular respiration is the process that creates chemical energy in the form of ATP from simple food molecules. These food molecules, particularly glucose, are first broken down in the cytosol outside the mitochondrion during glycolysis.

This begins aerobic cellular respiration. First, the citric acid cycle takes place in the mitochondrial matrix; this releases a few ATP and creates NADH and FADH2 electron carrier molecules that get passed along to the next stage, the electron transport chain.

These electrons are passed along by proteins embedded within the membrane and produce molecules of H2O. H+ ions (protons) from these carriers are shuttled 'across' the inner membrane and into the inter-membrane space between the inner and outer mitochondrial membranes.

H+ ions (protons) from these carriers are shuttled 'across' the inner membrane and into the inter-membrane space between the inner and outer mitochondrial membranes.The buildup of H+ ions in the inter-membrane space creates a proton potential. During chemiosmosis, the protons funnel through an ATP synthase protein in the inner membrane. As they do, the ATP synthase spins to create ATP from ADP and phosphate. Thus, the proton potential provides the energy for making ATP.
It is present in Mitochondria.
Hi, Here is ur answer
A crista is a fold in the inner membrane of a mitochondrion. The name is from the Latin for crest or plume, and it gives the inner membrane its characteristic wrinkled shape, providing a large amount of surface area for chemical reactions to occur on.
The main function of mitochondria is the use of carbohydrates to generate ATP through oxidative phosphorylation. Cristae membranes and cristae junctions are an integral part of this process. The folding or wrinkling of the cristae on the inner mitochondrial membrane creates a large surface area inside the mitochondria.
