Answer:
Glycolysis must occur before ATP is produced, regardless of whether it is fermentation or the citric acid cycle that follows. Because hexokinase is involved in this preliminary step, if its activity were stopped, the cell could not continue to produce ATP by either pathway.
Explanation:
Answer:
Concentration gradient
Explanation:
When the concentration of molecules and ions is compared to the concentration of ions and molecules in another area, the difference in the concentration will be called the concentration gradient.
The concentration gradient is the factor which determines the rate and direction of the molecules and ions in the environment which could be physical or biological.
Thus, concentration gradient is the correct answer.
