Explain why it is important to animals for the major carbohydrate storage polymer, glycogen, to be branched rather than unbranch

kolezko [41]

Answer: A branched polymer has greater terminal glucose residues in comparison to a unbranched polymer of the same molecular weight resulting in a higher number of terminal glucose residues required to be mobilized when energy is demanded. Enzyme and polymer evolve together to meet the dire need for rapid mobilization.

Explanation:

In comparison to an unbranched polymer, a branched polymer has a more compact and symmetrical molecular conformation with a greater terminal glucose residue. It can be broken down easily when energy is needed. For instance, the branched form of starch, amylopetin, in the small intestine starch is hydrolyzed to form glucose which is converted to biochemical energy and stored for later use.

when measuring the blood pressure, the cuff is deflated until two consecutive beats are heard through the stethoscope. This meas

dem82 [27]

Answer: Systolic pressure.

Explanation:

Every time the heart beats, it pumps blood into the arteries, which are vessels through which blood circulates from your heart to your tissues with the oxygen and nutrients they need. Blood pressure is the force of the blood pushing against the walls of the arteries, and is highest when the heart beats, pumping blood, which is measured as systolic pressure (i.e., when the heart contracts). On the other hand, diastolic blood pressure refers to the pressure of blood in the artery when the heart relaxes between beats (i.e., when the heart relaxes). Since there are two types of pressures, blood pressure readings are given in two numbers, with the top number being the systolic pressure and the bottom number being the diastolic pressure.

For example, if the systolic pressure measured in a person is 125 millimeters of mercury (mm Hg) and the diastolic pressure is 85 mm Hg, the blood pressure is recorded as 125/85.

So, the systolic blood pressure is registered with the stethoscope when the cuff is deflated. When two heartbeats are heard, the pressure gauge reading is recorded. When the heartbeat ceases, the cuff pressure is released and the diastolic pressure is measured at this time.
