Question

In glycolysis _____ ATP/NADH molecules are produced from 1 molecule of glucose. 1/2 5/3 2/3 1/12 2/2 _____ are chemical reactions that result in the breakdown of more complex organic molecules into simpler substances. Metabolism Catabolic Anabolism Reduction Oxidative Enzymes are _____ produced by living cells that catalyze chemical reactions by _____ the activation energy. Sugars Increasing Proteins Decreasing Lipids Maintaining Most enzymes are holoenzymes, consisting of a protein portion called _____ and a portion called cofactor. Apoenzyme Multienzymes Haloenzymes Monoenzymes Epienzymes

Explanation / Answer

8. Answer:

e. 2 ATP & 2 NADH

9. Answer:

b. Catabolic pathway (top-down process)

10. Answer:

c. Proteins (though all enzymes are proteins and enzymes are biocatalyst)

11. Answer:

d. Decreasing activation energy so that reaction can carry out very fast.

12. Answer:

a. Apoenzyme

The holoenzyme is an apoenzyme together & its cofactor. A holoenzyme is complete and catalytically active.
