Intro To Biochem LAB Flashcards
(26 cards)
Comes from bios, the Greek word for life
Bio
The study of substances found in living organisms, and of the chemical reactions underlying the processes of life
Biochemistry
The father of biochemistry
Dr. Carl Neuberg
The molecules present in the living cells
Biomolecules
Refer to any organic or inorganic matter which when introduced into the body,will either positively or negatively affect vital processes for the life, health and nutrition status of a living individual
Biomolecules
Example of this are sugars, fatty acids, nucleotide, amino acids
Small molecules
Examples of this are proteins, lipids,carbohydrates, and nucleic acids
Macromolecules
All higher living organisms including humans are made up of _____
Cells
Any cell that contains a clearly defined nucleus and membrane bound organelles
Eukaryotic cells
Any unicellular organism that does not contain a membrane bound nucleus or organelles
Prokaryotic cells
Examples of this cell are animals, plants, fungi, and protist cells
Eukaryotic cells
Example of this type of cell are bacteria and archaea
Prokaryotic cells
Cell size of an eukaryotic cell
Large (10-100 micrometers)
Cell size of prokaryotic cell
Small (less than a micrometer to 5 micrometers)
Replicates entire genome at once
Prokaryotic cells
Highly regulate with selective origins and sequences
Eukaryotic cells
Usually multicellular
Eukaryotic cells
Unicellular
Prokaryotic cells
It is the longer phase of the cell cycle where the cell is active and preparing for cell division
Interphase
The DNA molecule is duplicated exactly in a process called
DNA replication
each chromosome consists of two chromatids joined at the centromere
Prophase
chromosomes align at the center of the cell
Metaphase
chromatids separate at the centromere and migrate to opposite poles
Anaphase
two new nuclei assume their normal structure, and cell division is completed, producing two new daughter cells
Telophase
