Study Notes

Cellular Respiration

The balanced chemical equation for cellular respiration is not provided in the given text.
The molecule that drives cellular respiration is not specified in the given text.
Energy is immediately available for use by living cells in the form of ATP (adenosine triphosphate).

Glycolysis

Glycolysis can be best described as a pathway that occurs in the cytosol of cells.
At the beginning of glycolysis, glucose undergoes a modification called phosphorylation, where a phosphate group is added to glucose to form glucose-6-phosphate.
A kinase enzyme is responsible for adding a phosphate group to glucose, initiating glycolysis.
The step in glycolysis that generates ATP is not specified in the given text.
ATP is derived from the general category of nucleotides.

Energy Production

During anaerobic conditions, pyruvate is converted into lactic acid or ethanol.
During the conversion of pyruvate into an acetyl group, a carboxyl group is removed.
The products of glucose oxidation, NADH and FADH2, are essential for oxidative phosphorylation.

Citric Acid Cycle

The molecule that activates the Krebs cycle is acetyl-CoA.
ATP is produced during the conversion in the citric acid cycle, but the specific step is not specified in the given text.
The electrons added to NAD+ reduce it to form NADH.
Three NADH molecules are produced on each turn of the citric acid cycle.

Copyright and Module Information

According to Republic Act 8293, section 176, works of the Government of the Philippines are not protected by copyright.
The Government of the Philippines owns the materials borrowed for inclusion in the module.
A government agency or office may impose conditions for the exploitation of works of the Government of the Philippines for profit.
The module was reviewed and contributed to by various individuals, but their names are not specified in the given text.
For exploitation of works of the Government of the Philippines for profit, permission is necessary as per Republic Act 8293, section 176.
