C4b2a and C3bBb are both enzymes that cleave C3.

Here's the step by step explanation:

1. C4b2a and C3bBb are part of the complement system, which is a part of the immune system that enhances the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism.

2. These two enzymes are known as C3 convertases. Their main function is to cleave C3 into C3a and C3b.

3. C3a is an anaphylatoxin which means it can induce a local inflammatory response. It does this by increasing vascular permeability, smooth muscle contraction, and histamine release from mast cells and basophilic leukocytes.

4. C3b, on the other hand, can bind to the surface of pathogens leading to opsonization, which marks the pathogen for ingestion and destruction by phagocytes.

5. Therefore, the correct answer is "cleave C3".
