Answer:
Step 1. A carboxyl group is removed from pyruvate, releasing a molecule of carbon dioxide into the surrounding medium. (Note: carbon dioxide is one carbon attached to two oxygen atoms and is one of the major end products of cellular respiration. ) The result of this step is a two-carbon hydroxyethyl group bound to the enzyme pyruvate dehydrogenase; the lost carbon dioxide is the first of the six carbons from the original glucose molecule to be removed. This step proceeds twice for every molecule of glucose metabolized (remember: there are two pyruvate molecules produced at the end of glycolysis); thus, two of the six carbons will have been removed at the end of both of these steps.
Step 2. The hydroxyethyl group is oxidized to an acetyl group, and the electrons are picked up by NAD+, forming NADH (the reduced form of NAD+). The high- energy electrons from NADH will be used later by the cell to generate ATP for energy.
Step 3. The enzyme-bound acetyl group is transferred to CoA, producing a molecule of acetyl CoA. This molecule of acetyl CoA is then further converted to be used in the next pathway of metabolism, the citric acid cycle.
Answer: A scarcity of lemmings will cause for the population of snowy owls to decrease, as their resources have been limited.
Answer:
Carbon dioxide has also increased over the last 100 years-- from about 300 ppm to 370 ppm.
Explanation:
Mitosis results in the formation of two diploid cells while Meiosis results to the formation of four haploid cells. Mitosis is a process that takes place in the somatic cells; a cell that has doubled its genetic material divides to produce two diploid daughter cells while meiosis is a process that take place in the gamete cells where a doubled cell undergoes two rounds of division producing four haploid cells.
