Glycolysis is the very first step in extracting the energy from the bonds of sugar. This is the breakdown of glucose to pyruvates which releases energy. One molecule of glucose produces four ATP molecules. Glycolysis is an oxygen dependent metabolic pathway.

Answer from: des7900

The end products of glycolysis are 2 pyruvates, 2NADH, and 2ATP.

4ATPs are formed and 2ATPs are lost during this process.

The presence of oxygen directs the pyruvate into the mitochondria to produce 3 times more ATP thanglycolysis (aerobic reactions of cellular respiration).

Further Explanation:

The process by which energy is produced in absence of oxygen is known as glycolysis. Glycolysis occurs in all the cells that are living. Glucose, which is a six-carbon sugar is the primary need in this process. The entire process takes place in the cytoplasm of the cell. After glycolysis, the prokaryotic cells do not undergo any other cycle. Eukaryotic cells, because of the presence of mitochondria follows other cycles to produce more energy after glycolysis. The entire glycolysis process fetches 4 ATPs, two molecules of pyruvate, two molecules of NADH, at a loss of 2ATP molecules. The net gain of the process is 2ATP+2PYRUVATE+2NADH+WATER. The presence of oxygen leads to the direction of pyruvate molecules into the mitochondria of the cell where other aerobic cycles of respiration occurs. acetyl coenzyme is formed from the pyruvate which in turn reacts in other cycles primarily. The initiation and completion of Krebs cycle and ETC is because of the presence of oxygen.

Answer from: Quest

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student, including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as edutech.
