SKELETAL muscle is a complex tissue, rich in proteins, that is, subjected to continuous rearrangements, and this homeostasis is affected by many different types of stimuli and stresses.
Tropomyosins are contractile proteins which, together with the other proteins actin and myosin, function to regulate contraction.
Mitochondrial dysfunction in the SKELETAL muscle.
Altered proteome and post-translational modifications underlie mitochondrial dysfunction in human muscle pathologies.
Site-specific phosphorylation altered local structure of mitochondrial proteins
These are affects of protein functioning due to pathology in skeletal muscle protein
how do pathological states affect the skeletal muscle proteins and their functioning?
what is the difference between the functioning of GLUT4 transporter in skeletal muscle cells whereas the adipose cells?
What is the primary energy consuming process in RESTING skeletal muscle? How does energetic stress affect this process? I know the first part is protein synthesis but I'm not sure the second portion of the question
Answer following questions. (a)How are smooth muscle cells different from skeletal muscle fibers and cardiac muscle cells? (b)How are skeletal and cardiac muscle tissues similar to each other? How do these two types of muscle tissue differ from each other?
Why does a skeletal muscle cell need a neuromuscular junction as a component part? Skeletal muscle fibers are voluntary and thus must be stimulated by a neural impulse before they will contract. Through the neuron, the brain tells the muscle cell what proteins to produce and what wastes to pump out of the cell. The muscle cell needs to be told when to divide, such as when a person is exercising and needs more muscle. A neuron provides the necessary...
Cellular proteins Describe each of the following: enzymes, cytoskeleton, hormones, antibodies, receptors, skeletal muscle, channels/transporters/pumps.
Mutations in mitochondrial genes frequently produce diseases that affect the brain and skeletal muscle (mitochondrial encephalomyopathies). Why are these two tissues particularly sensitive to mitochondrial mutations?
Physiology Skeletal Muscle 1.) How does preload in an isolated muscle preparation relate to muscle tone in an intact organism?
Compare the rates of muscle contraction and relaxation of skeletal, smooth, and cardiac muscles. How do they differ? (5 pts) What relationship best describes the differences? Draw a figure to illustrate this. (5 pts) What are the differences mostly due to? (5 pts)
How does pH affect proteins? Why do proteins have an optimum, minimum, and maximum pH at which they will function?
ACTIVITY 1 Learning Skeletal Muscle Microstructure Materials for This Activity Compound light microscope Prepared slide of skeletal muscle (teased) Model of muscle cell showing parts of a myofibril View a slide of skeletal muscle, and carefully focus and adjust the light so that you can see the stria- tions, or alternating light and dark areas. The ligh areas are where we mainly have the thin act: proteins. The darker areas are where we mais have the thick myosin proteins. Now...
