Enzymes act as catalysts that remain unmodified as they increase the rate of a chemical reaction.
The correct answer is: Sodium and potassium ions move by active transport, and glucose moves by facilitated diffusion.
Because sodium and potassium are moved through cell membrane against their concentration gradients, transport requires energy (ATP), so it is active. <span>Glucose is a polar molecule and because the plasma membrane is impermeable to polar molecules transport of this important nutrient is accomplished by carrier proteins. This process is called facilitated diffusion and it is passive transport (doesn’t require energy).</span>
Electron Affinity is not far different from Electronegativity. It’s just that Electronegativity is the impulse of an atom to attract a shared pair of electrons (or electron density) towards itself and is much more often associated with molecules rather than each atom and the values could vary to some degree, although a single value is commonly used for most calculations in inorganic chemistry whilst Electron affinity is a fixed value of an individual atom.
The correct answer is Acromegaly.
Hypersecretion of hGH which causes overgrowth of the feet and hands, abnormal thickening of bones of the face, excessive overgrowth of soft tissue, which occurs after puberty is known as acromegaly.
The symptoms of acromegaly are enlargement of feet and hands, forehead, nose, and jaw.
This disease has some complications. For example, high blood pressure, sleep apnea, type two diabetes. Acromegaly results because of the pituitary gland which produces too much growth hormone.
