What is the purpose of the krebs cycle
It creates high energy molecules and ATP
what is the goal of cell replication
to create 2 genetically identical cells
who proposed the theory of evolution
charles darwin
What is the overall purpose of cellular respiration
To convert energy stored in glucose molecules into ATP
what enzyme is responsible for unwinding the dna double helix during replication
helicase
What molecule enters to start the krebs cycle to get the whole thing started
Acetyl CoA
What are the three main stages
Interphase, Mitosis and cytokinesis
what primarily drives evolution
natural selection
what is the initial stage of cellular respiration
glycolysis
during dna replication, what enzyme synthesizes a new dna strand by adding nucleotides in the 5' to 3' direction
dna polymerase
What are the 2 molecules that this cycle produces
NADH and FADH2
what are the significance of checkpoints
They reduce the chances of mutation from damaged dna
small changes in the genetic makeup of a population over generations that are the basis for evolution
mutations
What is glycolysis
when glucose breaks down into two molecules of pyruvate
short rna sequences that serve as starting points for dna synthesis during replication
rna primers
what is the process in which carbon dioxide molecules are released during the cycle
what is the different between mitosis and meiosis
Meiosis is for reproductive cells
term that describes the process where species with similar traits evolve separately due to different environmental pressures
divergent evolution
what is the purpose of oxygen in cellular respiration
It serves as the final electron acceptor in the electron transport chain
the enzyme that is responsible for joining the okazaki fragments on the lagging strand during dna replication
dna ligase
What do NADH and FADH2 do in the cycle
They are electron carriers that donate electrons
what is programed cell death
apoptosis
type of selection that occurs when individuals with intermediate traits have higher fitness that those with extreme traits
stabilizing selection
where does cellular respiration take place in the eukaryotic cells
the mitochondria
the process during dna replication that ensures high fidelity by correcting errors in newly synthesized dna strands
dna proofreading
