Explanation:
Metabolism in eukaryotic cells depends on the endoplasmic reticulum because it transports materials between membrane-bounded organelles within the cell.
Answer:
Glucose is co-transported with Na , which moves down its concentration gradient into the cell.
Explanation:
Na/K pump is a pump located on the plasma membrane which uses ATP to move 3 Na ions out the cell and brings in 2 K ions into the cell. It is an example of primary active transport. As a consequence,concentration of Na is higher outside the cell, while K concentration is higher inside the cell.
Glucose is transported in the cell against its gradient, together with Na ions (symport) which move down their concentration gradient.
This is an example of secondary active transport because it uses the energy from the primary active transport to move other substances such as glucose against their own gradients.
