What is the purpose of the inner membrane of mitochondria?

At the inner mitochondrial membrane, a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this drives hydrogen back through the membrane, through ATP synthase.
A.

Is the Cristae the same as the inner membrane?

The outer membrane surrounds the mitochondria. It is a semi-permeable membrane similar to the cell membrane. The folds created by the inner membrane are known as the cristae, which contain proteins and molecules that participate in cellular respiration.
  • Is the Cristae the same as the inner membrane?

  • What is the role of the inner mitochondrial membrane in ATP synthesis?

    This creates a concentration gradient of protons that another protein complex, called ATP synthase, uses to power synthesis of the energy carrier molecule ATP (Figure 2). At the inner mitochondrial membrane, a high energy electron is passed along an electron transport chain.
  • Why do mitochondria need the many folded inner membranes called the Cristae?

    The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix. The folding of the inner membrane increases the surface area inside the organelle.
B.

What is the function of the Cristae that are found inside the mitochondria?

The mitochondrial cristae are where electrons are passed through the electron transport chain, which pumps protons to power the production of energy molecules called ATP. NADH and FADH2 are molecules that carry electrons. The folds in this inner membrane are called the cristae.

  • What is the purpose of the cristae in the mitochondria?

    noun, singular: crista. (cell biology) The infoldings or inward projections of the inner membrane of the mitochondrion, which are studded with proteins and increase the surface area for chemical reactions to occur like cellular respiration.
  • What is the function of the inner membrane of the mitochondria?

    The structure of the inner mitochondrial membrane is extensively folded and compartmentalized. The numerous invaginations of the membrane are called cristae, separated by crista junctions from the inner boundary membrane juxtaposed to the outer membrane.
