Answer:
Option b oxaloacetate is the right one.
Explanation:
There are major eight steps in TCA cycle. Oxaloacetate plays a pivotal role in <u>first and eight step</u>s of cycle.
Step 1. In the first step of the citric acid cycle, acetyl CoA joins with a four-carbon molecule, oxaloacetate, releasing the CoA group and forming a six-carbon molecule called citrate.
Step 8. In the last step of the citric acid cycle, oxaloacetate—the starting four-carbon compound-is regenerated by oxidation of malate. Another molecule of NAD+ is reduced to NADH in the process.
Prokaryotic: has no nucleus, has no mitochondria.

Answer:
Isoniazid (INH) and rifampicin (RMP).
This is called MDR TB.
MDR TB is a particular type of drug resistant TB. It means that the TB bacteria that a person is infected with are resistant to two of the most important TB drugs, isoniazid (INH) and rifampicin (RMP). If bacteria are resistant to certain TB drugs this means that the drugs don’t work.
