Predict
Which crosses most easily without a transport protein?
Observe
The membrane is selective.
Suggested bridge
Charge and size would help here.
Your answer or confidence suggests one short foundation before transport proteins.
Bridge · Charge and size
The lipid core resists charged particles.
Sodium carries charge. Glucose is larger and polar. Both use membrane proteins instead of crossing the lipid core freely.
Apply
A bacterial cell needs glucose. What helps it cross?

Oxygen crosses the lipid bilayer more easily than glucose or sodium. Weak evidence can add a short charge and size bridge before the route returns to transport proteins.
Glucose uses a transport protein. Concourse packs describe concepts,
routes, activities, and evaluation in
pack.json, catalog.json,
courses.json, and items.json.
Adding a DNA side route changes the unpacked catalog and course draft before validation and export.
