Front

How do buffers work in biological systems?

Back

Buffers work by neutralizing excess acids or bases, maintaining a stable pH in biological systems.

Front

What triggers the release of glucagon?

Back

Glucagon is released when blood sugar levels are low, signaling the liver to release glucose.
