Intro to cells Flashcards
What is the smallest living unit in our body
The Cell
What the two major types of cells
Prokaryotic and Eukaryotic
What are some things that the Prokaryotic and Eukaryotic cells have in common
They both have the plasma membrane, DNA, cytoplasm, and ribosomes
Characteristics of a prokaryotic cell
-Smaller
-Simpler structure
-DNA concentrated in nucleoid region, which is not enclosed by membrane
-Lack most organelles
Characteristics of a eukaryotic cell
-Larger
-more complex structure
-Nucleus encloseed my membrane
-Contains many types of organelles
What do organelles do
Carry on essential functions of a cell
chemicals that speed up the rate of reaction between substances without themselves being consumed in the reaction.
What are enzymes
What is anabolism
synthesis of complex molecules from simple ones often requires energy
The breakdown of complex molecules to simple ones that usually require energy
What is catabolism
The sum of all chemical reactions in the cell
What is metabolism
Does a anabolic or catabolic reaction often require energy
Anabolic
Do a anabolic or catabolic reaction release energy
catabolic
Organisms that have no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops.
prokaryotic cell
Cell type that contains specialized organelles in the cytoplasm, a membrane-bound nucleus enclosing genetic material organized into chromosomes.
Eukayotic cell
