A peptide bond forms between the amino group of one amino acid and the carboxyl group of another, critical for protein synthesis. Active transport is the type of cell membrane movement that requires energy, moving substances against their concentration gradient using ATP. An example of active transport is the sodium-potassium pump, which maintains ion balance in cells.

A peptide bond is formed between the amino group of one amino acid and the carboxyl group of another, crucial for protein formation. Movement that requires energy across the cell membrane is known as active transport, which involves processes like the sodium-potassium pump. These concepts are fundamental in understanding protein structure and cellular functions. ;
