Biology 1
What part of DNA holds the genetic information?
Nitrogenous base
Cell that does not contain a nucleus or any other membrane-bound organelles. EX: Bacteria
Prokaryotic Cell
What is the importance of DNA replication occurring without any mistakes?
No mutations will occur
Why is DNA important?
It gives each cell instructions on how to do its job.
Most cellular respiration takes place in the
Mitochondria
Energy currency of cells
What is Adenosine Triphosphate (ATP)
Which biomolecule carries genetic information?
Nucleic Acid
Only organelle of a prokaryotic cell.
ribosome
What does a virus need in order to reproduce?
A host cell
Reactants of photosynthesis.
carbon dioxide, water, and light energy (sun)
Which organisms have the most available energy in a food pyramid?
Producers
Enzyme catalyzing starches.
Amylase
This is an enzyme's effect on the amount of energy needed to start a reaction.
Lowers activation energy.
A cell containing a nucleus and other membrane-bound organelles.
Eukaryotic Cell
Energy conversion of photosynthesis.
light energy to chemical energy
What do viruses have in common with living cells?
Genetic Information
A change in the sequence of nitrogen bases in a gene is called a
mutation
Ecological succession that results from most natural disasters.
Secondary
Biogeochemical cycle with no atmospheric stage.
Phosphorus
What are nucleotides made of?
phosphate, sugar & a nitrogen base
Which symbiotic relationship occurs when both organisms benefit from each other?
Mutualism
Protein is the product of what process?
transcription
2 of the 3 organelles containing DNA
nucleus, mitochondria, chloroplast
What is the purpose of cellular respiration?
To create ATP energy from glucose
energy conversions of cell respiration (2 of 3)
chemical energy to potential or kinetic or thermal energies
