Unformatted text preview: 7. What molecule enters glycolysis? Glucose molecule 8. Where in the cell does glycolysis occur? It occurs in the cytosol of the cell. 9. What are the products of glycolysis? The products of glycolysis are pyruvate, ATP, and NADH. 10. What type of molecule is NAD + ? What is its purpose? NADH+ is an oxidated electron carrier. The addition of two electrons and a proton to NAD+ produces NADH. 11. What molecule enters the Kreb’s cycle? Acetyl CoA molecule 12. Where in the cell does the Kreb’s cycle occur? In the inner matrix of the mitochondria 13. What are the products of the Kreb’s cycle? ATP, CO2, NADH, and FADH2 14. Fill in the blanks: When both glycolysis and the Kreb’s cycle are completed, glucose has been completely oxidized__ to ATP __ ....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
