15. While texting on your phone, the central nervous system directs your fingers by sending commands that are carried by_________________.
efferent neurons.
afferent neurons.
glial cells.
schwann cells.
None of the above
13. Energy can be harvested from the glucose molecule and generate ATP ONLY IF: (Select all that apply)
mitochondria are present within the cell
the cell has membrane proteins that can pump hydrogen ions (i.e., H+)
oxygen can accept electrons
the cell has enzymes that can catalyze reactions in glycolysis (i.e., PFK)
the cell can carry oxidation-reduction reactions
12. Marathon runners tend to do what is called "carbo loading" (that is, eat a lot of pasta) before their big race. Carbohydrates are source of energy because provide glucose to the cells. Why "carbo loading" is beneficial to the marathon runner?
The bonds in the carbohydrate/glucose have high potential energy
Through the process of anabolism the runner will break down the carbohydrate/glucose
The bonds in the carbohydrate/glucose have low potential energy making easily to chew
Makes the runner feel full for a longer period of time
9. Energy supports _____________________ to maintain homeostasis, which results in the well-being of the organism.
