Question
Chapter 41.3, Problem 1CSC
Summary Introduction
To determine: The advantages and disadvantages of having a child homozygous for the allele encoding for fast-twitch fibers.
Introduction: The long muscles generally contain the fast-twitch muscle fibers. There is a low requirement of the oxygen in fast-twitch muscle fibers. The mitochondria are fewer in the fast-twitch muscle fibers. The fast-twitch muscle fibers are white in color because there the level of myoglobin is low in these fibers.

3.4. About human skeletal muscle contraction, what are the correct statements?
PHYSIOLOGY_basic (OJO)
A muscle fiber is made by the parallel apposition of sarcomers.
Generation of force relies on the formation of cross-bridges between actin and myosin filaments.
In the process of contraction, adenosine triphosphate (ATP) is required both to drive the actin-myosin association-dissociation cycle and to recycle calcium back to the endoplasmic reticulum.
Each muscle fiber is innervated by one neuron only.
T tubules are plasma membrane invaginations of the sarcolemma that allow excitation-contraction coupling.

- The human body has mainly two types of muscle fibres: slow-twitch and fast-twitch. The { slow or fast} twitch contract slowly and resist fatigue and produce most of their energy through { aerobic or anaerobis} rispiration. These muscle fibres are best used for activities like { weight lifting and playing tennis or biking and jogging} The { slow or fast} twitch are adapted for the rapid regeneration of power. They can best be used in activities such as { weight lifting and playing tennis or biking and jogging}. They are rich in glycogen and depend on { aerobic or anaerobis} rispiration. to produce energy. This leaves them vulnerable to the accumulation of lactate and they fatigue quickly. which one are those? the answersarrow_forwardAfter death, a person no longer makes ATP, so calcium stored in the sarcoplasmic reticulum diffuses down its concentration gradient into the muscle cytoplasm.

- A typical relaxed sarcomere is about 2.3 μm in length and contracts to about2 μm in length. Within the sarcomere, the thin filaments are about 1 μmlong and the thick filaments are about 1.5 μm long.(a) Describe the overlap of thick and thin filaments in the relaxed and contracted sarcomere.(b) An individual “step” by a myosin head in one cycle pulls the thin filamentabout 15 nm. How many steps must each actin fiber make in one contraction?arrow_forwardCertain multi-headed myosins bind cooperatively to actin filaments. The binding interaction is mainly electrostatic in nature, so the presence of additional salt (ions) in solution can interfere with binding; ions will tend to associate with charged residues on the two proteins, blocking electrostatic attractions that would otherwise take place. Briefly describe the expected shape of the binding curve for one of these myosins, and what will happen to the shape when the salt concentration increases.arrow_forwardWeight training causes fast glycolytic fibers to hypertrophy (increase in diameter).
