Solution Summary

Different substrates enter either through glycolysis or through Kreb cycle to produce ATP. Carbohydrate enters through glycolysis and at different stages different number of ATPs are produced.

Glycolyis and Cellular Respiration

Answer the following questions in a 2- to 3-page paper:

1. What is the starting molecule in glycolysis (i.e., what is being metabolized. Be specific)?
2. Define these terms: substrate, enzyme, ATP, and describe why they are important in cellular respiration.
3. What do these enzymes do, generally speaking? Would the reaction occur if they were not present? Why or why not?
4. What are the byproducts of cellular respiration? Where do these byproducts end up (in the organism AND in the environment)?
