Products from cell culture are secreted to the media in active form True False

False.While some products *are* secreted in their active form, it's not true that *all* products from cell culture are secreted this way. Many products are secreted as inactive precursors (pro-proteins or pro-enzymes) that require further processing or modification (e.g., cleavage, glycosylation) to become active. This can happen either extracellularly or after uptake into another cell.
