Q

How does the electron chain work for oxidative phosphorylation?

A

NADH and FADH bring electrons and protons to the electron transport train(matrix), where then the electrons power a natural electric pump through the intermembrane of the mitochondria. A special molecule will direct the e- to the next pump and will power a new electric pump(h+) and a high concentration of H+ will be generated in the intermembrane of the mitochondria from NADH and FADH bringing 2 e- and 2 H+. Once the flow of electrons reaches the last pump, it will be made into H2O from O2 and the protons will be transferred to the ATP synthase where the concentration gradient of H+ will cause it to move through the synthase and will create power to make the ATP synthase make ATP.

107
Q

What occurs to the stimulated skeletal muscle when the closing of Na+ channels and the opening of K+ channels?

A

Repolarization, polarity is reversed from positive to negative. +30 mV to -90mV.

108
Q

What is the enzyme that integrates the ACh?

A

Acetylcholinesterase.

109
Q

When myosin heads bind to the exposed myosin binding sites on the actin forming a ____ between actin and myosin. Is this high or low energy myosin?

A

Crossbridge formation. It causes high energy myosin.

110
Q

The myosin head swivels toward the center of the sarcomere, pulling along the attached thin filament. This is called ____.

A

Power stroke(pull). This causes contraction of the muscle.

111
Q

What causes the power stroke?

A

When the ADP and phosphate group combined on the head of the myosin creating ATP. When ATP turns into ADP and phosphate group again and is detached, causing the power stroke.

112
Q

What causes relaxation(needs ATP)?

A

AChE breaks down the ACh, calcium pumped back into sarcoplasmic reticulum and limits duration of contraction.

113
Q

Characteristics of calcium pumps on SR?

A

Calcium pumps of SR membrane transport 2 Ca2+ into SR and 2-3 H+ out.

114
Q

What are the 10 steps of muscle contraction and relaxation?

A

(contraction)ACh releases binding to receptors, action potential reaches T-tubes, sarcoplasmic reticulum releases Ca2+, active-site exposure and crossbridge binding, contraction begins. (relaxation)ACh removed by AChE, SR recaptures Ca2+, active sites covered and no crossbridge interaction, contraction ends, relaxation returns to resting length.

Q

What is the secondary messenger to successfully start contraction?

A

Calcium ion.

116
Q

What is one cause of muscle fatigue?

A

Runs of glycogen(ATP).

117
Q

Supplying energy needs by ____

A

Glycolysis(2 quick ATP).

120
Q

What is the long term supply of energy?

A

Aerobic respiration(oxygen required).

121
Q

What is oxygen debt?

A

When oxygen demand is greater than oxygen supply. So you borrow O2 from somewhere else.

122
Q

During oxygen debt where is O2 taken from?

A

Hemoglobin(pigments in red blood cells), myoglobin(pigments in muscle cells).

123
Q

What causes one muscle twitch?

A

One single muscle contraction in response to AP.

When muscle stimulations occur in the span of 10-20 stimuli/sec without being able to reach full relaxation this is called ____.

A

Treppe.

129

Why does treppe occur?

A

Each twitch develops more tension, calcium is not returned, heat of tissue increases myosin ATPase efficiency(ADP→ATP).
