What is a Peptide bond?
What is a Peptide bond?
A type of bond that links amino acids together in a protein chain, formed by removing a molecule of water when the carboxyl group of one amino acid reacts with the amino group of another.
What is Glycolysis?
What is Glycolysis?
The breakdown of glucose into two pyruvate molecules, generating ATP and NADH. This process occurs in the cytoplasm of cells and is a key pathway in cellular energy production.
What is Gluconeogenesis?
What is Gluconeogenesis?
The process of synthesizing glucose from non-carbohydrate sources, such as amino acids or glycerol. It helps maintain blood glucose levels during times of fasting or starvation.
