In the first step of cellular respiration, also known as glycolysis, a six carbon molecule is converted into
a. glucose ; pyruvic acid
b. glucose ; atp
c. atp ; glucose
d. pyruvic acid ; glucose

The first step of cellular respiration is glycolysis, where a six carbon glucose is broken down into a three carbon, this is called pyruvic acid. You're welcome

If you want the other steps in cellular respiration or cytology, just ask, I'm an A+.

When a virus infects a host cell, it uses the cell's machinery to make copies of its own genetic material in a process called replication. finally, during the process of self-assembly, that protein shell and the copies of the virus's genetic material are assembled into new viruses.
