Question:
Identical pathways that make up the complicated sequence of reactions of glycolysis, shown in Panel 13–1, are found in most living cells, from bacteria to humans. One could envision, however, countless alternative chemical reaction mechanisms that would allow the oxidation of sugar molecules and that could, in principle, have evolved to take the place of glycolysis. Discuss this fact in the context of evolution.
Panel 13–1
Transcribed Image Text:
STEP 1 Glucose is phosphorylated by ATP to form a sugar phosphate. The negative charge of the phosphate prevents passage of the sugar phosphate through the plasma membrane, trapping glucose inside the cell. STEP 2 A readily reversible rearrangement of the chemical structure (isomerization) moves the carbonyl 4K oxygen from carbon 1 to HỎ carbon 2, forming a ketose from an aldose sugar. (See Panel 2-4, pp. 72-73.)

I have been a tutor for 2 years and have experience working with students of all ages and abilities. I am comfortable working with students one-on-one or in small groups, and am able to adapt my teaching style to meet the needs of each individual. I am patient and supportive, and my goal is to help my students succeed.
I have a strong background in math and science, and have tutored students in these subjects at all levels, from elementary school to college. I have also helped students prepare for standardized tests such as the SAT and ACT. In addition to academic tutoring, I have also worked as a swim coach and a camp counselor, and have experience working with children with special needs.
