Cells & Enzymes
What organelle is the command center for the cell, containing the genetic material?
Nucleus
How are the equations for photosynthesis and cellular respiration related?
What are two differences between DNA and RNA?
DNA: Double stranded, contains Thymine, cannot leave the nucleus
RNA: Single stranded, contains Uracil, can leave the nucleus as messenger RNA
Which phase of mitosis does the nuclear membrane dissolve?
Prophase
What is natural selection?
Organisms with traits better suited for their environment are more likely to survive and reproduce
Osmosis
What are the reactants of photosynthesis?
Water, CO2, Sunlight
What is the name of the process for reading a strand of DNA to synthesize a strand of RNA?
Transcription
Which phase of mitosis consists of spindle fibers arranging chromosomes in the middle of the cell?
Metaphase
What is the name of the symbiotic relationship in which both organisms benefit?
Mutualism
What organelle produces proteins for the cell?
Ribosome
What are the products of photosynthesis?
O2 and Glucose
What is the name for the process of reading a strand of mRNA to create a chain of amino acids (protein)?
Translation
Which phase of mitosis involves the cytoplasm and non-nuclear contents dividing?
Cytokinesis
What is the name of the symbiotic relationship in which one organism benefits while the other is being harmed?
Parasitism
What are two organelles found only in plant cells?
Cell Wall & Chloroplast
What are the products of cellular respiration?
CO2, Water, ATP (energy)
A to U, T to A, C/G
Which phase of meiosis produces the final four daughter cells?
Cytokinesis II
What is the name of the symbiotic relationship in which one organism benefits while the other remains unaffected?
Commensalism
The enzyme is the (lock/key) while the substrate is the (lock/key). What is something that could cause an enzyme to denature?
Enzyme = lock, substrate = key
pH or temperature outside of optimal range
What color light is the least successful in growing plants? Why?
Green; plants reflect green light
Use your codon chart to translate the following mRNA transcript into a chain of amino acids:
AUG CCC GGA UGA
Met - Pro - Gly
What is the connection between cancer and the cell cycle?
Cancer occurs when the cell cycle is unregulated, resulting in uncontrolled cell division
Why did the peppered moths in England change color from light to dark during the Industrial Revolution?
Soot covered their environment, making it darker; the moths with darker colors were able to camouflage and hide from predators, making them more likely to survive than light colored moths
