The correct answer is 20% on average. The ideal percentage rate of a healthy man with normal weight is 18 to 22%. However, a range of 7-13% is considered normal for male professional athletes, because their muscular mass is much greater. The physiological minimum rate which is acceptable for males is 4-6%.
Answer:
Glycolysis produces 4 ATP molecules, giving it a net gain of 2 ATP molecules. The four high energy electrons that are removed by glycolysis are picked by an electron carrier called NAD. NAD becomes NADH.As it spins it grabs an ADP molecule and attaches a phosphate, forming high energy ATP.
Explanation:
Both NADPH and ATP are phosphorylated compounds, both are very important catabolic as well as anabolic processes. To explain the difference, their respective functions/roles in biochemical processes should be described along with relevant chemical properties.
ATP (Adenosine triphospahte) is called an energy rich molecule because of the large negative free energy of its hydrolysis (And has nothing to do with high bond energy).
30.5 kilo Joules or 7.3 kilo calorie energy is liberated after hydrolysis of one ATP molecule to form ADP (Adenosine diphosphate) and phosphate.The reaction is almost irreversible
Answer:
<u>
They have hydrophilic heads and hydrophobic tails.</u>
Explanation:
Phospholipid membranes are comprised of a chain of lipids. These typically are arranged in a bilayer; the hydrophilic lipid heads are polar, and face outwards, while the hydrophobic tails are polar facing inwards.
The membranes are selectively permeable, and only allow the movement of small, non-polar molecules through the bilayer.
Answer:
Meteorologists forecast tornadoes through the measurement of temperature, air speed and pressure conditions to monitor atmospheric conditions

Baroreflex is a reflex triggered when a baroreceptor is stimulated. In the human body, baroreceptors are found in the carotid sinuses and the sinus of the aorta. These receptors are stimulated during changes in blood pressure. Baroreceptors are sensitive to the stretching of blood vessels.
As blood pressure rises, baroreceptors transmit nerve impulses to the vasomotor center of the medulla oblongata, which is then inhibited. This results in vasodilatation of the blood vessels to reduce blood pressure.
