Biology
Playing the piano requires activation of muscles of the upper limbs, neck and back. to play the keys, the fingers must generate rapid, small movements that vary in force generation to play the keys sometimes very hard (larger amounts of force) and sometimes very soft (very little amounts of force), and everything in between. the elbow flexors hold the elbow joint at the same comfortable angle throughout the duration of play, which can last several hours. additionally, the player must also sit upright at the piano bench for these long durations without the back or neck muscles fatiguing. a. lactic acid is produced because no oxygen is available to the muscle cell. b. lactic acid is made when atp demands exceed oxygen availability in the cell. c. lactic acid is a byproduct of creatine phosphate production. d. lactic acid is made when there is insufficient glucose in an active cell

Ответ:
The correct answer will be option- B
Explanation:
Cells undergo cellular respiration to produce energy in the form of ATP molecules which are used for other reactions. The cellular respiration depends on the presence of oxygen as oxygen acts as an electron acceptor.
When cells lack the availability of oxygen and the demand for ATP increases more than the oxygen available, the cell shifts its mechanism from aerobic respiration to anaerobic respiration to supply extra ATP required.
The cell does this by converting pyruvate to lactic acid which acts as an electron acceptor and thus helps produce NAD⁺ which allows the formation of ATP molecule through repetition of the steps.
Thus, option- B is the correct answer.
