The normal pulse rate for humans is usually 60 to 100 beats per minute, however, there are certain medical conditions such as cardiac arrhythmia which may alter the normal pulse rate of an individual. Other influencing factors include your age, gender and fitness level.
Aldosterone is a hormone secreted by the adrenal cortex, and insulin is a peptide secreted by the pancreas. When aldosterone contacts a target cell, it binds to an intracellular receptor and migrates to the nucleus; insulin binds to extracellular receptors on the plasma membrane. What is the most likely reason for this difference? a. Aldosterone is hydrophilic and therefore must enter the aqueous environment of the cytoplasm to have an effect. b. Aldosterone is lipid-soluble and therefore easily crosses the phospholipid bilayer of the plasma membrane.
A Riverside Health System answered. Aldosterone belongs to a class of hormones called mineral corticoids, also produced by the adrenal glands. Aldosterone helps maintain blood pressure (BP) and water and salt balance in the body by helping the kidneys retain sodium and excrete potassium.
