What is the purpose of the intermembrane space in chloroplast?
Table of Contents
The intermembrane space is a compartment of very small volume since the outer and inner membranes are in very close proximity. Only a relatively small number of components of the intermembrane space are known, most of which are required for mitochondrial biogenesis or have a function in energy metabolism.
What is produced in the intermembrane space of mitochondria?
During electron transport, the participating protein complexes push protons from the matrix out to the intermembrane space. 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).
What is the function of the intermembrane compartment of the mitochondria quizlet?
The main function of mitochondrial intermembrane space is oxidative phosphorylation. The mitochondrial inner membrane is the site of the electron transport chain, an important step in aerobic respiration. Between the inner membrane and outer membrane is the inter-membrane space.
What is the importance of the inner membrane?
The inner or cytoplasmic membrane, impermeable to polar molecules, regulates the passage of nutrients, metabolites, macromolecules, and information in and out of the cytoplasm and maintains the proton motive force required for energy storage.
What happens in the Intermembrane?
the intermembrane space: holds protons that are pumped out of the matrix during electron transport, the inner mitochondrial membrane: organizes the electron transport chain and holds ATP synthase, the cristae: expand the surface area of the inner mitochondrial membrane, enhancing its ability to produce ATP, and.
Why is the double membrane of the mitochondria important?
The mitochondrion has a primary role in energy metabolism, a role that is intimately connected with its double-membrane structure (outer and inner, each comprising a lipid bilayer). Formation of mitochondria (mitochondrial biogenesis) is under the dual control of the nuclear and mitochondrial genetic systems.
What is the purpose of the cristae membrane quizlet?
Mitochondrial cristae are folds of the mitochondrial inner membrane that provide an increase in the surface area. This allows a greater space for processes that happen across this membrane. The electron transport chain and chemiosmosis are the processes which help produce ATP in the final steps of cellular respiration.
What is the inner space of the mitochondria called?
The space inside the middle of Mitochondria is called Matrix whereas peripheral part is called cortex.
How does structure of mitochondria relate to its function?
The structure of the mitochondrion is adapted to the function it performs: Outer membrane – the outer membrane contains transport proteins that enable the shuttling of pyruvate from the cytosol. Inner membrane – contains the electron transport chain and ATP synthase (used for oxidative phosphorylation)
What is the proton motive force?
Energy that is generated by the transfer of protons or electrons across an energy-transducing membrane and that can be used for chemical, osmotic, or mechanical work.

What is the inner space in mitochondria?
Inner Membrane. The inner or cytoplasmic membrane,impermeable to polar molecules,regulates the passage of nutrients,metabolites,macromolecules,and information in and out of the cytoplasm and maintains the proton
What are the inner membranes of mitochondria?
What is the inner membrane of mitochondria made of? The mitochondrial inner membrane is made primarily of a phospholipid bilayer, just like the cell membrane. Embedded in this bilayer are various proteins that serve to carry out the electron transport chain. The membrane has folds called christae that increase its surface area.
How many inner membranes does the mitochondria have?
The mitochondria are suspended in the jelly-like cytosol of the cell. They are oval-shaped and have two membranes: an outer one, surrounding the whole organelle, and an inner one, with many inward protrusions called cristae that increase surface area.
