Have a longer half-life Have a shorter half life Are water-soluble Are lipid-soluble Can cross the cell membrane Cannot cross the cell membrane Can interact with receptors on the cell surface Can interact with receptors in the nucleus or cytoplasm Applications (q 10-12, 2 points each): Use the below information to answer the remaining questions.

Due to government funding cuts, you have recently been appointed as head physiologist for the Centre for Disease Control, due to your unparalleled physiology knowledge and willingness to work for minimum wage. Billions of people served worldwide by the popular fast food chain McDowell’s have all fallen ill due to a mysterious chemical being used in the beef.

You are tasked with gathering as much information as possible about this chemical with a view to treating those affected. Note: When people stop eating at McDowell’s, they are no longer affected, but apparently that isn’t an option, especially at 1:00am, nor is it an option to change the beef.

The chemical leads to a dramatically increased heart rate. Through animal testing, you determine that the chemical increases heart rate by acting directly on the heart itself and affects autonomic nervous system signaling. It appears to have no direct effect on blood vessels. You have not determined if it is affecting other organ systems.

Assuming the drug only acts on one type of receptor, which of the following receptors could it potentially be acting on, given the above information?

(select all that apply): Acting on nicotinic receptors of both sympathetic and parasympathetic postganglionic neurons. Acting on muscarinic receptors. Acting on beta-1 adrenergic receptors. Acting on beta- 2 adrenergic receptors. Acting on alpha-1 adrenergic receptors. Acting on alpha-2 adrenergic receptors:

The net products of glycolysis in a musele cell are:$$(1\mathrm{pt}$$.)$$1\mathrm{NADH}$$2 ATP 2 lactates 2 pyruvates 7. The reactions of glycolysis occur in the cell’s ; the reactions of the citric acid cycle occur in the (1.pt.) 8. When energy is released during catabolism, it is temporarily trapped in high-energy bonds of electrons of certain compounds. Which of the following is NOT associated with carrying potential energy? ( 1 pt) ATP FAD$$\mathrm{FADH}3$$NAD*$$\mathrm{NADH}$$Physical exercise results in skeletal muscle contraction, an active process that requires chemical energy in the form of ATP. Initially, small amounts of ATP are available within the skeletal muscle fibers.

The available ATP may sustain contractions for about 15 seconds before the ATP needs to be replenished. Cellular respiration is one mechanism by Which muscle fibers produce and replenish their ATP. Cellular respiration increases the avallability of ATP by consuming oxygen and glucose while producing water and carbon dioxide as a waste byproduct.

Thus, during exercise, as the metabolic activity of the muscle fibers increase, the concentration of oxygen in the muscle tissue decreases. Other byproducts of metabolic activity (temperature, acidity, and CO2 concentrations) likewise increase with metabolic activity. The increased presence of these metabolic byproducts is detected by specific homeostatic sensors that send out signals to the local vasculature and cause vasodilation, thereby shifting blood flow from less active tissues to the nearby exercising muscles.

The greater flow of blood into the exercising muscle resolves the oxygen loss while simultaneously removing the waste and other byproducts of the increased metabolic activity. (2 pts.) 9. Number the following 1.5 in the order in which the events occur: Blood deliver to the skeletal muscle increase in order to provide more oxygen. Skeletal muscle metabolism increases. You start to exercise. Oxygen sensors cause local blood vessels to dilate. Skeletal muscle oxygen demand increases:
