Question

organelles are specialized structures in eukaryotic cells and are surrounded by one or more membranes. which definition is more correct regarding the purpose of these membranes? they ensure that the enzymes cant react with other enzymes. they ensure that the internal conditions are different to the external environment.

Explanation:

Organelle membranes create distinct internal environments. Enzymes within organelles can interact with substrates (not just avoiding other enzymes). The key is maintaining unique internal conditions (e.g., pH, ion concentrations) different from the external (cytoplasmic) environment for specific organelle functions.

Answer:

They ensure that the internal conditions are different to the external environment.
