Why are proteins and polysaccharides cannot be transported across a cell membrane by carrier proteins?
They are too large to be transformed by carrier proteins. They are moved across by Vesicles instead.
Why proteins and polysaccharides cannot diffuse through the membrance?
They are too large and usually contain hydrophilic regions which prevent movement across the hydrophobic core of the plasma membrane.
What happens if a molecule is too large to go through a membrane?
The molecule will be transported across the membrane by way of a transport protein or protein channel.
What occurs in wind erosion A. Wet soil is transported away. B. Dry soil is transported away C. Small rocks are left behind. D. Large rocks are left behind.?
Large rocks are left behind and dry soil is transported away. B- Dry soil is transported away in a process called deflation
When is active transport needed?
When large materials are being transported through the membrane

How do larger molecules move across epithelial membranes in the capillaries?
Large molecules are transported across a cell membrane by the process of process of exocytosis. This is when secretory vesicles secretes large molecules by the fusion of vesicles with the plasma membrane.
Who takes the chocolate around the world?
Chocolate is transported around the world in many ways. Across large land continents and countries, chocolate is transported by mail, truck, and train. It can go in the cargo of airplanes and ships, too, when traveling across seas or just much further distances.
What type of molecule embedded in the cell membrance allows larger molecule to pass through the membrance by active transport?
Transport proteins allow the active transport of large molecules through the cellular membrane.
What are large rocks transported by?
Glaciers
All the solutes are filtered out except proteins (large molecules) during?
Glomerular filtration
How are goods and services transported in Mexico?
Services cannot be transported. That being said, most goods are transported by either truck or rail transport. Export goods also can include large oil tankers or large container ships.
How copper ores are transported?
Via extra large trucks.

Large rocks are left behind and dry soil is transported away. B- Dry soil is transported away in a process called deflation
How is water transported or distributed in Romania?
Using a large system of tubings.
