🤔 If a drug blocks the Na⁺/K⁺ pump (primary active transport), what happens to glucose absorption in the gut (secondary active transport)? Answer: It stops—no sodium gradient, no glucose cotransport.
Primary active transport, also known as direct active transport, involves the direct use of ATP (adenosine triphosphate) to transport molecules or ions across the cell membrane. In this process, the energy from ATP hydrolysis is used to pump molecules or ions against their concentration gradient. The most well-known example of primary active transport is the sodium-potassium pump (Na+/K+-ATPase), which maintains the resting potential of neurons and other excitable cells. primary active transport secondary active transport
This process is called . To pull this off, the cell must spend energy. Biologists categorize this into two distinct mechanisms: Primary Active Transport and Secondary Active Transport . 1. Primary Active Transport: Direct Energy Use 🤔 If a drug blocks the Na⁺/K⁺ pump
