Answer:
A proteins coated with phospoholipids
Explanation:
Because proteins are large component and passing through a cell membrane that have large size is hard. But if you have similar quality with the cell membrane, it can pass through so that the pharmacy industry use this technique for hormones etc.
Answer:
C. carrier proteins
Explanation:
The core of the cell membrane is made up of hydrophobic tails of phospholipid. It does not allow the water-soluble material to move across the membrane. Carrier proteins are the membrane proteins that serve as transporters.
The carrier proteins bind the ion or water-soluble molecules and undergo changes in shape. This transports the molecule across the membrane. Carrier proteins serve in passive facilitated diffusion and active transport. The carrier proteins involved in facilitated diffusion transport the molecules down the concentration gradient without any expenditure of energy.
We can reduce air pollution by using public transport instead of private vehicles when possible, this can reduce the gas released from private cars. We can reduce energy consumption by setting air conditioner to a suitable temperature such as 26°C or use fan instead. Also make sure we turn off all the electrical appliances when we leave a place.
