BIOCHEMISTRY Flashcards
is the study of the composition of living matter & the changes which occur in it.
Biochemistry
the science concerned with the chemical basis of life.
Biochemistry
the science concerned with the chemical constituents of living cells & with the reactions & process they undergo
Biochemistry
Study of biomolecules/ micromolecules
Biochemistry
Name the Biomolecules
Nucleic Acids
Carbohydrates
Lipids
Proteins
Give the building blocks of each biomolecules
Nucleic Acids - DNA, RNA
Carbohydrates - Monosaccharides
Lipids - Fatty Acids
Proteins - Amino Acids
Genetic material template for protein synthesis
Nucleic Acids
Usually they are the molecules of the cell that carry out work (ex:enzymes)
Proteins
Short term of energy as (glycogenstorage from of glucose)
Carbohydrates
Numerous functions (ex: membrane components of the long term storage of energy as fat)
Lipids
basic unit of Life
is the structural & functional unit of biology
Cells
bilayers, composed mainly of proteins & lipids
for barrier & protection
Cell Membrane
Protein embedded outside cell membrane
receptors
Peripheral
Protein embedded within cell membrane
ion-channel
Integral
are structure with the specific shapes & specialized functions & are characteristic of eukaryotic cell
Organelles
contains genetic material that manufacture nucleic acid
control center of the cell -(genetic material found in nucleus)
Nucleus
Nucleus composed of three regions:
nucleolus (nucleoli) where RNA & proteins synthesized/site of ribosome assembly
Nuclear membrane or envelope
Chromatin (Chromosomes)
Nucleus composed of three regions:
nucleolus (nucleoli) where RNA & proteins synthesized/site of ribosome assembly
Nuclear membrane or envelope
Chromatin (Chromosomes)
manufacturer & shipper
ER
major function of ER
Glycosylation
a membranous network in eukaryotic
cells connecting the plasma membrane
w/ the nuclear membrane
ER
a membranous network in eukaryotic
cells connecting the plasma membrane
w/ the nuclear membrane
ER
site of acylglycerol synthesis
ER
w/ ribosomes on its surface
for protein synthesis w/c mostly glycosylated
Rough ER
w/out ribosomes on its surface
for lipid synthesis
Smooth ER
factory sites of Protein synthesis
Ribosomes
Prokayotes - __ (Sub-units: __s & __s)
Eukaryotes - __ (Sub-units: __s & __s)
Prokayotes - 70S (Sub-units: 50s & 30s)
Eukaryotes - 80S (Sub-units: 60s & 40s)
storage site/ packaging counter of the cells
Golgi Apparatus
attachment of CHON in CHON products
Golgi Apparatus
storage of CHON - undergo modification - glycosylation
Golgi Apparatus
”suicide sacs” (kill or destroy foreign organisms)
Lysosomes
containing digestive/ hydrolytic enzymes
Lysosomes
Lysosomes are present only in _ cells
animal cells
2 types of lysosomes
Peroxisomes and Macrophages
A lysosome which oxidizes amino acids, fatty acids & alcohols and use molecular oxygen to detoxify harmful substances
Peroxisomes
A lysosomes which eat foreign maté
Macrophage
storage tank of the cell
Vacuole
an intracellular inclusion
Vacuole
VACUOLE
in eukaryotic surrounded by _
in prokaryotic surrounded by _
VACUOLE
in eukaryotic - surrounded by a plasma membrane
in prokaryotic - surrounded by proteinaceous membrane
location of the ETC (Electron Transport Kreb’s Cycle)
Mitochondria
organ fro respiration, redox reaction, glycolysis, etc
Mitochondria
ATP synthesis occurs in the _ Mitochondria.
Inner
performs photosynthesis in photoautotrophic eukaryotes
Chloroplast
helpers in cell division
Cetrosome
involved in formation of the mitotic spindle
Cetrosome
CYTOPLASM
▪in prokaryotic cell: everything _
▪in eukaryotic cell: everything i_
CYTOPLASM
▪in prokaryotic cell: everything inside the plasma membrane
▪in eukaryotic cell: everything inside the plasma membrane, & external to the nucleus
is the selectively permeable membrane enclosing
the cytoplasm of a cell
Plasma membrane
where glycolysis & PPP found
Cytosol
fluid/ liquid portion of sytoplasm
Cytosol
microfilaments, intermediate filaments, & micortubules that provide support & movement for eukaryotic cytoplasm
Cytoskeleton
the movement of cytoplasm in a
eukaryotic cell
Cytoplasmic Streaming
are small, extrachromosomal circular DNA molecules found in prokaryotes
Plasmid
carry _ genes
are _ DNA molecules
are found in many types of bacteria
_ independently of the main chromosomes
*Each cell may contain several copies of plasmids
Plasmid
carry optional genes
are circular DNA molecules
are found in many rypes of bacteria
replicate independently of the main chromosomes
*Each cell may contain several copies of plasmids
are small basic proteins that participate in forming the nucleosomal structure of the chromatin
Histones
where fatty elongation occurs
Microsomes
helps in the removal of danaged cell
contains a bactericidal agent such as lysozyme that kills bacteria before it damages the cell
Lysozyme
