Week 6 Questions 1.) How does the sodium gradient achieved by the pump facilitate food acquisition (sugar) ? Gradient means the concentration. Potassium (k) is going in and sodium is going out (Na). We need this pump because we are running out of energy inside the cell2 Ks are coming in and 3 sodiums are going out. Net flow is one outside. High concentration of ions outside. Because the NA is knocking on the cell, the co-transport canal allows for the capture of sugar from outside to inside is used as energy. It is able to do this because the concentration outside is higher. 2.) Describe the Calcium pump. Which way does calcium go? Is energy required? Calcium is getting pumped out. Because it is getting pumped out it means that you need ATP--> ADP, so yes energy is required. 3.) Know which side (in or out) of every living prokaryotic cell has more hydrogen, sodium, potassium, and calcium. A cell is going to have potassium in. it is going to pump sodium
