Consider the following states for these molecules: Concentration
of each on the OUTSIDE of the cell, relative to the INSIDE of the
cell: Ca2+=higher; Amino Acid=lower; Glucose=lower; Oxygen=higher;
K+=lower; Cl- = higher, Na+=higher.
Answer the following question in relation to these molecules.
Which of the molecules/ions would required energy to move from the Inside to the Outside?
A. Cl-, Ca2+
B. Cl-, oxygen, and Ca2+
C. AA, Glucose, and K+
D. Cl-, Ca2+, Na+
Homework Answers
C. AA, Glucose, and K+
| Inside | Outside |
| Amino acid | Calcium |
| Glucose | Oxygen |
| K+ | Chloride |
| Sodium |
According to the question, the inside concentration of amino acids, glucose and K+ is lower inside than outside hence amino acids, glucose and K+ moves from inside to outside and requires the expenditure of energy.

HW 11-1 Recall that the Na + concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill" transport of two Na + ions into the cell to the "uphill" transport of glucose into the cell. If the Na + concentration outside the cell ( [ Na + ] out ) is 149 mM and that inside the cell ( [ Na + ] in ) is 19.0 mM, and the cell potential is −...

Consider a secondary active transporter that uses symport for two molecules, X and Y. If X is the molecule being actively pumped and Y is present in higher concentration inside the cell, which of the following is true? (It might be helpful to sketch out the situation to visualize it better.) Xis present at higher concentrations inside the cell. X is being pumped from outside the cell into the cell. Xis present at higher concentrations outside the cell. Y is...

At 37 °C the equilibrium concentration of Ca2+ inside a cell is 0.098 M and outside is 0.019 M. The cell membrane is permeable to Ca2+ and Cl–. The only ion present in addition to Ca2+ and Cl– is a protein (Prin+/–) inside the cell. The protein holds a single positive or negative charge. The Cl– is at equilibrium across the membrane while the protein is inside the cell and cannot permeate the membrane. What is the concentration of Prin+/–...

At 37 °C the equilibrium concentration of Ca2+ inside a cell is 0.067 M and outside is 0.034 M. The cell membrane is permeable to Ca2+ and Cl–. The only ion present in addition to Ca2+ and Cl– is a protein (Prin+/–) inside the cell. The protein holds a single positive or negative charge. The Cl– is at equilibrium across the membrane while the protein is inside the cell and cannot permeate the membrane. What is the concentration of Prin+/–...

Many cells take up molecules against their concentration gradients: the molecules are more concentrated inside the cell than outside. Amino acids are frequently transported in this fashion. For the question below, think about intestinal cells growing in medium that is equivalent to blood. The concentration of amino acids is higher in the cell's cytoplasm than in the medium outside the cell. Please indicate whether each of the following modes of transport would permit amino acid uptake into the cell. For...

5/2400 Resources Give Up Hint Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Nat-glucose symporter. Recall that the Nat concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill" transport of two Nations into the cell to the "uphill" transport of glucose into the cell. If the Na+ concentration outside the cell (INa1.) is 151 mM and that inside the cell ([Na]) is 23.0 mm, and the cell...

1. Animal cells have a Na,K pump that couples the energy of ATP hydrolysis to transport 3 Na ions out of the cell and 2 K ions into the cell. Inside astrocytes, the concentration of Na is 20 mM and the concentration of K is 130 mM. The extracellular concentrations of Na and K are 145 mM and 5 mM, respectively. Calculate the energy required for the transport of Na and K , with this stoichiometry; assume that the cell...
