Two criteria that would identify the three muscle tissues are myofibers and nuclei.
There are three types of muscles:
1. Skeletal-Contains many nuclei along the length of the muscle cell. The nuclei are displaced peripherally. The skeletal fibers are arranged parallel. The myofibril is composed of bands.
2. Smooth-This tissue contain spindle-shaped cells with a single central nucleus. Smooth muscle fibers are shorter than skeletal.
3. Cardiac-The fibers of cardiac muscle are not simply parallel. Cardiac muscle fibers are long cylindrical cells with one or two nuclei.
Answer:Glycolysis: (p. 94; Fig. 6.7A-C)
Refers to:
Occurs:
Energy investment phase: Steps 1 – 4 C-C-C-C-C-C
2 ATP
How many ATP's required (used)?
Results in 2 molecules of 3 phosphoglyceraldehyde (G3P) C-C-C C-C-C
Note: Step 5 is an isomeration step between G3P & Dihydixyacetone phosphate
Energy yielding phase: Steps 6 – 10 (G3P) C-C-C C-C-C
Explanation:
The answer is; A
When an impulse from the motor neuron reached the neuromuscular junction, the voltage-dependent calcium channels are activated and the neurotransmitter released from the presynaptic cleft. When the neurotransmitter binds to their receptors on the sarcolemma, the muscle fibers become depolarised; the calcium is released from their vesicles. The Ca2+ ions are important in the power stroke because they bind to troponin. Upon binding calcium, troponin moves tropomyosin away from the myosin-binding sites on actin. Powered by the energy from ATP molecule, the myosin is able to bind on the actin and slides over the actin filament.
Pain due to an injury can tell about the organ affected. The pain in the right shoulder refers to an injury of the liver organ, Thus, option d is correct.
<h3>What are abdominal and genitourinary injuries?</h3>
Abdominal and genitourinary injuries are damages to the organs and tissues of the digestive and excretory system that mostly affects the liver, kidneys, spleen, etc.
The liver is an organ located in the right upper abdomen involved in various functions and bodily activities. Shoulder pains are associated with liver injuries as inflammation and discomfort affect the neck and shoulder region.
Therefore, option d. the liver is the affected organ.
