Water
Which type of bond is H2O?
Covalent Bond
What is cohesion?
When two water molecules bond together.
True or false.
Catabolism is the same that Anabolism.
False. They are completely opposite.
What are monomers?
Small and simple molecule that acts as the basic unit to build up larger polymers.
Function of Proteins
Produce hormones, and build and repair muscles and bones.
Which are the two elements that form water?
Hydrogen and Oxygen.
What is adhesion?
When hydrogen bonds form between water and other polar molecules (one side positive and another negative), causing water to stick to them.
Which one releases energy and which one needs energy.
Catabolism: releases energy
Anabolism: the process needs energy.
What is the simplest form of carbohydrates? And Functional group.
MONOSACCHARIDES (glucose, fructose, ribose)
Hydroxyl -OH
Function of Carbohydrates
Primary source of energy to the body and help control blood glucose.
What is a hydrophobic substance? Examples
Substances that are insoluble in water although they dissolve in other solvents. Ex. All lipids (fats and oils).
Thermal property.
High latent heat vaporization.
When a molecule evaporates the liquid molecules separates to become vapor --- the heat needed to do this is called latent heat vaporization.
What are things that Catabolism and Anabolism share?
The two process are required to the proper functioning of the body.
Are types of metabolism.
What are the simplest form of lipids?
Functional group.
Fatty acids.
Carboxyl group
-COOH
Function of lipids
They help with moving and storing energy, absorbing vitamins and making hormones.
What are the hydrophilic substances? Examples
Substances that dissolve in water and are attarcted to water. Ex. glucose, sodium and chloride Ions.
Thermal property.
High specific heat capacity.
Large amount of energy is required in order to increase the temperature of water to break these hydrogen bonds. Cool down--loose energy.
What is Catabolism?
Breakdown of complex molecules into simpler molecules.
What are the simplest form of proteins?
Functional group.
Amino acids.
Carboxyl group -COOH
Amine group -NH2
Elements present in proteins.
Carbon, hydrogen, oxygen, nitrogen, sulfur.
What is a hydrogen bond?
Chemical bond of water molecules. It happens in the negative charge of the molecule (Oxygen) and the positive part (Hydrogen).
Thermal property.
High boiling point.
Boiling point=the highest temperature that a substance can stay in a liquid state. Water remains liquid in 00C to 1000C.
What is Anabolism?
Is the synthesis of complex molecules from simpler molecules.
What are the simplest form of NUCLEIC ACIDS?
NUCLEOTIDES
Functional group of NUCLEIC ACIDS
carboxyl groups (−COOH) in amino acids, methyl groups (−CH3), and phosphate groups (–PO3)
