Glycolysis

Glycolysis is the first step in breaking down glucose to produce energy, occurring in the cytoplasm of all living cells without the need for oxygen. It converts one glucose molecule into two pyruvate molecules, releasing energy captured as ATP and producing NADH for later energy production stages. This ten-reaction process is vital for providing quick energy and building blocks for other metabolic pathways.

Glycolysis

Glycolysis is the first step in the process of breaking down glucose, a type of sugar, to
produce energy for cells. It happens in the cytoplasm of all living cells and does not require
oxygen, so it can occur in both aerobic (with oxygen) and anaerobic (without oxygen)
conditions.

During glycolysis, one molecule of glucose (which has six carbon atoms) is broken down into
two molecules of pyruvate (each with three carbon atoms). This process releases a small
amount of energy, which is captured in the form of ATP (adenosine triphosphate), the energy
currency of the cell. Glycolysis also produces molecules called NADH that carry electrons to
later stages of energy production.

Glycolysis involves a series of ten chemical reactions, each catalyzed by specific enzymes. It
is a crucial pathway because it provides energy quickly and supplies building blocks for other
metabolic processes.

In summary, glycolysis is the initial and essential process that breaks down glucose into
pyruvate, releasing energy that cells use to perform their functions.
