Energy Substrates
This metabolic pathway proceeds without oxygen, occurs in the cytosol of the cell, produces low ATP, and animals (including humans) cannot survive on this system alone. (Bonus high five: how many ATP does it yield)
What is the Anaerobic pathway. (2)
What neurotransmitter and channel is housed in the presynaptic somatic motor neuron terminal?
What is Acetylcholine and Calcium?
This thin filament is covered in two proteins (name them) and is anchored at each end of the sarcomere by Z lines.
What is actin? Troponin and tropomyosin.
What is homeostasis and sympathetic (f/f) + parasympathetic (r+d)
Which fiber types are slow v fast twitch?
What is: Type 1 is slow and Type 2 is fast?
This type of metabolic pathway takes place in the mitochondria and requires oxygen and time. (Bonus: How many ATP)
What is Aerobic? (Net total: 32)
What does ACh bind with and where?
What is NAChR and postsynaptic membrane?
This thick filament has specialized projections called cross bridges.
What is myocin? (ends in heads)
Which ANS releases ACh onto a postganglionic cell (notes also have this cell as Nicotinic Cholinergic Receptors)?
What is BOTH!
What is the difference between the two fast twitch fibers?
What is: Fast Oxidative-Glycolytic (2A) is a combo of Type 1 and Type 2X and Fast Glycolytic (2X) is large diameter, pale color and easily fatigued.
What are the three transitional energy systems?
What are: Phosphogen, Glycolitic, and Oxidative?
What creates the end plate potential?
What is the sodium/potassium pumps?
When is the sliding filament theory initiated?
When is the Ca binds to the troponin?
ATP is converted into potential energy and used in muscle action*
Which ANS releases norepinephrine onto Adrenergic Receptors on a target cell?
What is the SNS?
This type of muscle is darker in color, smaller in diameter, and fatigue resistant.
What is Type 1?
How many ATP, pyruvate, and NADH does glycolysis yield?
What is: 2 ATP, 2 pyruvate, and 2 NADH?
What is the region of the muscle membrane that contains a large amount of nAChR receptors?
What is the motor end plate?
This giant protein acts as a spring and spans across half of the sarcomere, centering the thick filament.
What is titin?
Which hormone released by the anterior pituitary is sent to the liver and aids in tissue healing? ?
What is it growth hormone?
Which type of fiber pumps calcium into their sarcoplasmic reticulum more rapidly?
What is Type 2?
What all does the electron transport chain yield?
What is: 10 NADH and 2 FADH for 28 ATP?
When is the NMJ formed?
When is the alpha motor neurons synapse with skeletal muscle fibers?
This stabilizer forms a scaffold around a sarcomere.
What is the Desmin?
True or False: Muscle fiber types are fixed for life.
What is false?
