Question

11 mark for review which of the following would most likely occur if cattle lost the ability to maintain a colony of microorganisms in their digestive tract? a cattle would no longer be able to synthesize cellulose. b cattle would have to convert cellulose to starch before digesting it. c cattle would have to start producing enzyme b without the help of the bacteria. d cattle would no longer be able to use cellulose as a primary source of glucose.

Explanation:

Cattle rely on microorganisms in their digestive tract to break down cellulose into glucose. Without these microorganisms, they cannot digest cellulose effectively and thus would no longer be able to use cellulose as a primary source of glucose. Cattle do not synthesize cellulose themselves (A is wrong), they don't convert cellulose to starch (B is wrong), and the information about enzyme B is not given in the main - question context to support C.

Answer:

D. Cattle would no longer be able to use cellulose as a primary source of glucose.
