The cell membrane is made mostly ofÂ
How do large and/or polar molecules pass through the plasma (cell) membrane?
Carbohydrates in the cell membrane provide the main source of energy for the cellÂ
the cell membrane is made solely of carbohydrates which gives the cell strength and structure
The two layers of phospholipids allow small non-polar molecules to pass freely through the membrane
The two layers of phospholipids make it difficult for large, hydrophilic substances to pass freely through the membrane
the membrane is made solely of proteins, this allows the cell to carry out all necessary reactions under unfavorable conditions
Sucrose is a type of sugar (carbohydrate). Sucrose is dissolved in water so it is the solvent. The sucrose molecule is too large to pass through the membrane. Why does one cell get larger, one cell gets smaller, and one cell stays the same?
What mechanism causes sodium and potassium ions to move through the sodium-potassium pump?
The concentration of solutes inside and outside of cells impacts the cells’ structure and ability to function. If a saltwater plant cell is placed in a solution that contains a low concentration of solute, how would the cell’s structure be impacted?
The concentration of solutes inside and outside of cells impacts the cells’ structure and ability to function. If a freshwater plant cell is placed in a solution that contains a high concentration of solute, how would the cell’s structure be impacted?
Organic molecules are composed mainly of carbon.
Water is an example of an essential cellular organic molecule
Organic molecules can be in the form of long chains and rings
Most organic molecules are able to diffuse through the cell membrane
Most of the organic molecules in animals come directly from the foods they eat
Organic molecules include carbohydrates, nucleic acids, proteins, and lipids.
sugars such as glucose and fructose, main source of energy, structural support
includes enzymes, a part of cell membrane, catalyzes reactions (makes reactions happen faster), provide structure and support for cells (think muscles)
fats, steroids, and oils, long term energy storage, signaling, water insolubility to protect cells (cell membrane)
DNA and RNA, contain genetic code
Which type of organic molecule codes all the information in a cell?
Which statement is not true about this cell?
What statement is true about this cell?
What is true of both prokaryotic and eukaryotic cells?
Which statement is not true of Eukaryotic cells
cell organelle that is responsible for the production of lipids and the folding of proteins.
What is the role of the Golgi complex in a cell?
