Lesson 1 Introduction To Biochem In Nursing Flashcards
is the chemistry of biological systems
Biochemistry
lifeless but they compose living things
Molecules
Building blocks are called
Monomer
Macromolecule are called
Polymer
Solar energy is transferred into
ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate)
What elements are biomolecules composed of?
carbon, oxygen, hydrogen, nitrogen, phosphorous, and sulfur
-make up >97% of the weight of most organisms
-form stable covalent bonds
major component of cells
Water
more abundant in living organisms than it is in the rest of the
universe
Carbon
six abundant elements
CHNOPS
Why is carbon so predominant in living systems?
because of the ability of carbon atoms to bond together to form long chains and rings
The composition of carbon atom
Nucleus has 6 protons and 6 electrons
2 she’ll layer that has 6 electrons
Carbon can form immensely diverse compounds, from simple to complex.
True
react chemically to produce biomolecules such as amino acids, sugars (monosaccharides), nucleic acids, fatty acids, glycerol.
Precursors or metabolites (H O, CO , NO -, NH + 2234
and N2)
These biomolecules are building blocks or monomers for the formation of the polymers which are
macromolecules
Macromolecules are assembled into
supramolecular complexes
is the set of chemical reactions that happen in living organisms to maintain life.
Metabolism
- do not have a membrane-bound nucleus or other organelles
Prokaryotes
2 classes or lineages of prokaryotes
eubacteria and archaea (thermoacidophiles, halophiles and methanogens)
● - possess nucleus and other organelles
Eukaryotes
e.g Enzyme complexes, ribosomes,chromosomes
Supramolecular Complexes
Proteins, Carbohydrates, Lipids, DNA, RNA
Macromolecules
(Building Blocks) Amino acids, Sugars, Fatty acids, Glycerol, Nucleic acids
Biomolecules
Pyruvate,citrate, succinate, Glyceraldehyde 3 phosphate, Fructose-1,6-bisphosphate
Metabolites
H O, CO , NH +, NO - and N
Precursors
