Boogie Man(CFU)- Cell membrane and Cell Transport

Front

What are the main components of the cell membrane?

Back

The main components of the cell membrane are phospholipids, proteins, cholesterol, and carbohydrates.

Front

What is the function of proteins in the cell membrane?

Back

Proteins in the cell membrane serve various functions including transport, acting as channels or carriers, and facilitating communication between the cell and its environment.

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy (ATP).

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, moving from high to low concentration.

Front

Define hypotonic solution.

Back

A hypotonic solution is one where the concentration of solutes outside the cell is lower than inside the cell, causing water to enter the cell.

Front

Define hypertonic solution.

Back

A hypertonic solution is one where the concentration of solutes outside the cell is higher than inside the cell, causing water to leave the cell.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves from inside the cell to the outside solution, leading to cell shrinkage.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, which may cause the cell to swell and potentially burst.

Front

What is the role of cholesterol in the cell membrane?

Back

Cholesterol helps to stabilize the cell membrane's fluidity and structure, making it less permeable to very small water-soluble molecules.

Front

What are phospholipids?

Back

Phospholipids are molecules that make up the cell membrane, consisting of a hydrophilic (water-attracting) 'head' and two hydrophobic (water-repelling) 'tails'.
