BIOC Exam 2 Glycolosis Gluconeogenesis

medschool student Q1

What types of cells carry out glycolosis

ALL CELLS

With glycolosis, how many reactions are performed and are they the same or vary for different cells. What else is different among different cells?

10 reactions- essentially the same in all cells

the rates differ

What is the first phase of glycolosis

converts glucose to 2 x glyceraldehyde-3-P

What does the 2nd phase of glycolosis produce

2 pyruvates

from the 2 phases of glycolosis, what are the products?

pyruvate, ATP, NADH

Is step 1 of glycolysis reversible or irreversible? Why?

Not reversible because of phosphorylation of the glucose molecule in the cell cytoplasm.
