IMM comprises of critical membrane proteins and enzymes, including those from electron transport chain (ETC), ions, and metabolite transporters such as the adenine nucleotide translocase (ANT), the mitochondrial calcium uniporter (MCU), and ATP synthase essential for the survival of cell.
The inner membrane of Mitochondria is deeply folded to create a large surface area for chemical reactions of oxidative phosphorylation, i.e. the process of converting food sugars into energy (ATP) to take place.
Jared’s symptoms involved out-of-control rage when startled, constant thoughts and memories of death-related events, weekly vivid nightmares of combat that caused trouble sleeping, anxiety and a loss of interest in hobbies he once enjoyed with friends.
Cristae are folds of the inner mitochondrial membrane. … The cristae increase the surface area of the inner membrane, allowing for faster production of ATP because there are more places to perform the process.
Part of cell respiration happens by transferring molecules across the inner membrane, so by adding folds, a longer piece of membrane can be stuffed inside the mitochondria. This increases the amount of molecules that can be transferred across it. Increasing surface area can be seen in many other parts of the body too.
Peroxisomes are small, membrane-enclosed organelles (Figure 10.24) that contain enzymes involved in a variety of metabolic reactions, including several aspects of energy metabolism.
PEROXISOME – the organelle behind the film ‘Lorenzo’s Oil’ Peroxisomes are small rounded organelles found free floating in the cell cytoplasm. These structures contain at least 50 enzymes and are separated from the cytoplasm by a lipid bilayer single membrane barrier.
How are peroxisomes more like mitochondria than like the membrane-bound organelles of the endomembrane system? … They do not form a part of endomembrane system. They independently form from the peroxin protein. The free ribosomes synthesize the peroxins, which are incorporated into the existing peroxisomes.
Types of Folds
How to Draw Clothing Folds: 6 Different Types
There are three basic types of folds (1) anticlines, (2) synclines and (3) monoclines.
The electron transport chain is the final step in cellular respiration. It uses the electron carrier molecules NADH and FADH2 created during the Krebs cycle. This process occurs along the inner membrane of your mitochondria.
They are made of two membranes. 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. Since many of the chemical reactions happen on the inner membrane, the increased surface area creates more space for reactions to occur.
Mitochondria is called as a strange organelle as it has its own DNA and Ribosomes . Plastids too have their own DNA and Ribosomes . … Both mitochondria and plastids are known as strange organelles as they have their own DNA and ribosomes. Thus replicate independent of nucleus and synthesise their own proteins.
Cyanide caused Jared’s symptoms because ETC stops working which makes O2 stop leaving, causing Jared’s symptom of shortness of breath that he was feeling.
Cyanide prevents the cells of the body from using oxygen. When this happens, the cells die. Cyanide is more harmful to the heart and brain than to other organs because the heart and brain use a lot of oxygen.
The mechanism of toxicity occurs because cyanide stops the cells of the body from being able to use oxygen, which all cells need to survive. The symptoms of cyanide poisoning are similar to those experienced when hiking or climbing at high altitudes, and include: General weakness.
Why is it important that the inner membrane of the mitochondria be folded in both plant and animal cells? The folded membrane increases the structure strength of the mitochondria. The folded membrane increases the surface area for energy production.
Each mitochondrion has two membranes: an inner membrane which is highly convoluted and folded into finger-like projections called cristae, and a smooth outer membrane that is a selective barrier to molecules from the cytoplasm.
Otherwise, the inner membrane is impermeable to most ions and small molecules—a property critical to maintaining the proton gradient that drives oxidative phosphorylation. … This is because it contains proteins called porins, which form channels that allow the free diffusion of molecules smaller than about 6000 daltons.
Peroxisomes are found in all eucaryotic cells. They contain oxidative enzymes, such as catalase and urate oxidase, at such high concentrations that in some cells the peroxisomes stand out in electron micrographs because of the presence of a crystalloid core (Figure 12-31).
