What are the four key biomolecules, and their percentage in a cell?
Lipids – 3%
Proteins – 18%
Carbohydrates – 4%
Nucleic acid 0.25% + 1.1% = 1.35%
Describe Catabolic pathways.
Catabolic pathways release energy by breaking down complex molecules into simpler compounds.
Cellular respiration is an example of a catabolic pathway.
Describe anabolic pathways.
Anabolic pathways consume energy to build complex molecules from simpler ones.
The synthesis of protein from amino acids is an example of anabolism.
What did Carl Neuberg do?
He discovered elucidation of compounds of sugars degradation and alcoholic fermentation and metabolic pathways.
Carbohydrates serve as a primary source of energy. What is its monomers and what type of bond joins the monomers?
Monosaccharides joined by glycosidic bond.
What are the elements in Carbohydrates?
C, H, O
(Carbon, Hydrogen and Oxygen).
Lipids serve as a secondary source of energy. What is its monomers and what type of bond joins the monomers?
Fatty acids and glycerol joined by ester bonds.
What are the elements in lipids?
C, H, O
(Carbon, Hydrogen and Oxygen).
Proteins are structural and functional units of the human body. What is its monomers and what type of bond joins the monomers?
Amino acids joined by peptide bond.
What elements are in proteins?
C, H, O, N, S
Carbon, Hydrogen, Oxygen, Nitrogen and Sulfur.
Nucleic acids are responsible for the reproduction of genetic materials. What is its monomers and what type of bond joins the monomers?
Nucleotides joined by phosphodiester bond.
What elements are in Nucleic acids?
C, H, O, N, P
Carbon, Hydrogen, Oxygen, Nitrogen and Phosphorus.
What does ATP stand for?
Adenosine triphosphate
