Consider the following statements regarding the Biosynthesis (Synthesis) phase:

Statement I: "Early proteins" synthesized during viral infection are typically enzymes needed for viral DNA replication and to halt host cell metabolism

Statement II: "Late proteins" include structural components like capsid proteins and tail fibers, which are synthesized after the viral genome has been replicated.

Which of the above statements is/are correct?

#Biochemistry

During strenuous exercise, the NADH formed in the glyceraldehyde 3-phosphate dehydrogenase reaction in skeletal muscle must be reoxidized to NAD+ if glycolysis is to continue.  The most important reaction involved in the reoxidation of NADH is:

#Biochemistry

The overall △G for glycolysis is -72 kJ/mol in erythrocytes. Which statement below is true?

A) The value of △G0ʹ is also -72 kJ/mol since the cytosol pH is close to 7.

B) The free energy of glycolysis is found as the sum of the standard free energy changes for

the individual pathway reactions.

C) The negative sign of △G shows that this pathway will proceed toward product (pyruvate) under normal cellular conditions.
