When we rest immediately after completing an intense workout, our muscles will soon switch from:

a. lactic acid fermentation to aerobic respiration
b. aerobic respiration to alcoholic fermentation
c. alcoholic fermentation to aerobic respiration

The right answer is A. lactic acid fermentation to aerobic respiration.

Unlike aerobic exercise, anaerobic exercises involve intense physical effort and short, causing anaerobiosis in the muscles which forces them to switch to anaerobic respiration which is lactic fermentation (producing lactic acid and ATP (energy) from pyruvate), followed by a rest period, again providing oxygen to the muscles, allowing them to switch back to aerobic respiration.

An anaerobic exercise has the function of muscle, it does not burn fat. Nevertheless, by increasing muscle mass, it requires to spend more calories.

A - lactic acid fermentation to aerobic respiration

Explanation:

I just completed the test :))

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
