Pasteur's work with the French wine industry proved all of the following except

That microbes can cause disease

Autotrophs exist among both eukaryotes and prokaryotes; each can vary in terms of how they capture energy to form ATPs, but they all have one very important feature in common that classifies them as autotrophs. What is a characteristic that varies among autotrophs?

only two of A, B, and C can vary among autotroph

Which is a false statemen

two of the above are false statements

The following represent different catabolic pathways that yield energy from the oxidation of an energy source. The electron donors in A‐E are oxidized; the electrons from these donors are ultimately transferred to a final electron acceptor as shown below. If light energy was also involved in the process, which of these reactions would represent photosynthesis as cyanobacteria carry it out?

) H2O NADP+

Which is false regarding bacterial endospores?

) molecule B

Glucose oxidation is completed and ATP, NADH, andFADH2 are formed

*A) in the Krebs cycle

Which is false regarding catabolic processes?

A) They release energy. B) They lead to the formation of smaller molecules from larger, complex molecules. C) They are coupled to (linked to) ATP formation reactions, i.e., ADP + P ATP. *D) None are false; A‐C are true statements

E. Two of the above

E represent different catabolic pathways that yield energy from the oxidation of an energy source. The electron donors in A‐E are oxidized; the electrons from these donors are ultimately transferred to a final electron acceptor as shown below. Assuming light energy were not part of the process, which of these reactions would represent chemoautotrophy (i.e., lithotrophy)?
