at the end of glycolysis, there is 2 G3P molecules. there is also 2 CO2, 2ATP, 2 NADH
glucose. it is broken in the cytoplasm
Glucose is the beginning molecule that begins the cascade of events that produces energy for the cell.
Glycolysis produces 2 pyruvate, 2 NADH, and 2 ATP [net]
This is the Glycolysis pathway Glycolysis (the breakdown of glucose to pyruvate and lactate, occurs in the cell cytoplasm): Glucose + 2 ATP + 4 ADP + 2 NAD -> 2 Pyruvate + 2 ADP + 4 ATP + 2 NADH + energy. Oxidation of glucose is known as glycolysis. Glucose is oxidized to either lactate or pyruvate. Under aerobic conditions, the dominant product in most tissues is pyruvate and the pathway is known as aerobic glycolysis. When oxygen is depleted, as for instance during prolonged vigorous exercise, the dominant glycolytic product in many tissues is lactate and the process is known as anaerobic glycolysis. "These studies demonstrate that orderly glycolysis in the erythrocyte is regulated by the NAD-to-NADH ratio and also provide a method that makes possible the in vitro study of erythrocyte glycolysis." The conversion of pyruvate to lactate, under anaerobic conditions, provides the cell with a mechanism for the oxidation of NADH (produced during the G3PDH reaction) to NAD which occurs during the LDH catalyzed reaction. This reduction is required since NAD is a necessary substrate for G3PDH, without which glycolysis will cease. Normally, during aerobic glycolysis the electrons of cytoplasmic NADH are transferred to mitochondrial carriers of the oxidative phosphorylation pathway generating a continuous pool of cytoplasmic NAD NADH
Glycolysis produces large quantities of NADH producing large amounts of energy. Glycolysis can also be carried out throughout the cell, which gives it an advantage over the TCA and Oxidative phosphorylation cycles that occur in the mitochondria. (:
Glucose
Pyruvic acid, also called pyruvate, is produced during glycolysis when the glucose molecule is split.
During Glycolysis, Glucosemolecules are split into two pyruvates during a sequence of enzyme-controlled reactions. This occurs in both aerobic and anaerobic respiration.
NAD+ is the molecule that is regenerated for glycolysis during fermentation. NAD+ is essential for glycolysis to continue in the absence of oxygen by accepting electrons from glucose breakdown.
The 3-carbon molecule produced when glucose is broken in half in glycolysis is pyruvic acid. It gives energy to living cells through the Krebs cycle.
During glycolysis, ATP is both consumed and produced. Two molecules of ATP are consumed in the initial steps of glycolysis to activate the glucose molecule. However, four molecules of ATP are then produced during the later steps, resulting in a net gain of two ATP molecules per glucose molecule metabolized.
During glycolysis, the overall gain of ATP per glucose molecule is 2. While glycolysis produces 4 ATPs, it uses 2 ATPs in the process.
