Membrane proteins called pumps use energy to move hydrogen ions to one side of the membrane. Which term describes the difference between the numbers of hydrogen ions on opposite side of the membrane?

Difference between the numbers of hydrogen ions on opposite side of the membrane is described by the term electrochemical gradient.

Explanation:

The electrochemical gradient refers to the amount of electrically charged ions found in two spaces separated by a membrane, as is the case with ions in the extracellular and intracellular spaces. In this case, hydrogen ions generate a gradient both by their chemical concentration and by the electric charge that such concentration implies.

An electrochemical gradient can be generated:

A difference of charges on both sides of the cell membrane. A concentration gradient, given the difference in quantities of the ions inside and outside the cell.

The use of a protein that pumps hydrogen ions is due to the fact that, sometimes, the ions must move against an electrochemical gradient.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.

The correct answer is  b)
