Carbon dioxide (chemical formula CO 2) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth’s atmosphere as a trace gas.The current concentration is about 0.04% (410 ppm) by volume, having risen from pre-industrial levels of 280 ppm.

Aug 01, 2018  · In fact, the last time the atmospheric CO 2 amounts were this high was more than 3 million years ago, when temperature was 2°–3°C (3.6°–5.4°F) higher than during the pre-industrial era, and sea level was 15–25 meters (50–80 feet) higher than today. Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.

Glycolysis can be divided into two phases: energy consuming (also called chemical priming) and energy yielding. The first phase is the energy-consuming phase, so it requires two ATP molecules to start the reaction for each molecule of glucose.However, the end of the reaction produces four ATPs, resulting in a net gain of two ATP energy molecules.
