Microsomal enzymes are typically found in the endoplasmic reticulum of hepatocytes. Microsomes are fragments of endoplasmic reticulum and attached ribosomes that are isolated together when homogenized cells are centrifuged.

Where are non-microsomal enzymes found?

Where are non-microsomal enzymes present? Explanation: Non-microsomal enzymes include those that are present in soluble form in the cytoplasm and those attached to the mitochondria but not to the endoplasmic reticulum.

Are microsomes present in live cells?

In cell biology, microsomes are heterogenous vesicle-like artifacts (~20-200 nm diameter) re-formed from pieces of the endoplasmic reticulum (ER) when eukaryotic cells are broken-up in the laboratory; microsomes are not present in healthy, living cells.
