Which ultrastructural observation would most strongly suggest a cell is highly metabolically active and producing large amounts of ATP?
Show answer and explanation
Correct answer: Abundant mitochondria with cristae
A high number of mitochondria with well-developed cristae under EM indicates robust capacity for oxidative phosphorylation and ATP generation, characteristic of metabolically active cells.
