a crystal whose molecules are held together by weak physical bonding as opposed to chemical bonding. They usually are soft and have low melting points. They are also poor conductors of electricity basically due to the lack of electrons and ions in these solids. Examples of molecular crystals are- ice, solid carbon dioxide( dry ice) and rock candy. Iodine, phosphurus, sulphur, nitrogen, argon and water all form molecular crystals.

Are Organic molecules are made from a small collection of simple precursors?
Organic molecules are molecules that have a carbon backbone.
What are carbohydrate molecules made up as?
Carbohydrate molecules are made up of small sub-units called sugars. Carbohydrates also contain the elements hydrogen, oxygen and carbon.
What are the limitation of simple diffusion using the amoeba as an example?
Simple diffusion really says it for itself. Mostly simple molecules and substances can pass through. Water, O2 or CO2, or other small simple molecules are the limited spectrum of simple diffusion.
Matter is made up of small particles called atoms or molecules?
true
What are pathways that require energy to combine molecules together called?
Anabolic pathways require energy to combine simple molecules into more complex ones.
Are most protein molecules small and simple to understand?
no
Are Organic molecules are made from a small collection of simple precursors?
Organic molecules are molecules that have a carbon backbone.
Simple molecules are further broken down in cells in a process called?
Simple molecules are further broken down in cells in a process called catabolism.
What are the simple sugars made up of?
Starches... Starches are large molecules made of small simple sugar molecules.
What is large molecules to small molecules called?
cell wall
What are carbohydrate molecules made up as?
Carbohydrate molecules are made up of small sub-units called sugars. Carbohydrates also contain the elements hydrogen, oxygen and carbon.
What is it called when small molecules build up larger molecules?
This process is called synthesis.
What are the limitation of simple diffusion using the amoeba as an example?
Simple diffusion really says it for itself. Mostly simple molecules and substances can pass through. Water, O2 or CO2, or other small simple molecules are the limited spectrum of simple diffusion.
What are the special proteins that can break large molecules into small molecules?
These substances are called enzymes.
The first person who proposed that small organic molecules could have arisen by chemical evolution of simple inorganic molecules was?
Aleksander Oparin
Nutrient molecules pass from the small intestine into the bloodstream through tiny structures called what?
Nutrient molecules pass from the small intestine into the through tiny structures called villi.
What types of molecules pass through the membrane rapidly?
Small non-polar molecules can pass through a membrane rapidly.
