Alex is participating in a 50 meter dash. Predict the most important chemical process his muscles will rely on during this race.
natta225 [31]

Answer: The correct answer to the question is option E

BOTH ANAEROBIC RESPIRATION AND CREATININE PHOSPHATE BREAKDOWN.

Explanation: 50 meter dash is a race,a form of exercise, energy is required as well as muscle contraction and chemical processes.

Alex muscles will rely on the following chemical processes during the race;anaerobic respiration and creatine phosphate breakdown.

These chemical processes are explained below;

Aerobic respiration uses oxygen to generate energy but unlike aerobic respiration, anaerobic respiration breaks down glucose to provide energy and create adenosine triphosphate(ATP), lactic acid and ethanol.

Muscle contraction cannot take place without the supply of energy by ATP, molecules can store energy in it's phosphate form, this molecule is known as creatine phosphate,when this happens,ATP that is in excess will then transfer it's energy to creatine,this action will produce creatinine phosphate and adenosine diphosphate (ADP) and they will now be stored as reserve of energy that can be used to produce more ATP and thus energy is produced.

How could the flood have been responsible for the formation of fossils?
iVinArrow [24]
The Biblical flood would have caused the death of all life on earth, except for those on the arc, which would have resulted in fossils that are now found. Fossils being found in different layers of rocks could have been a result of how they settled as the waters receded.
