Unit 1
What is the process of moving molecules WITH the concentration gradient?
Diffusion. or simple diffusion.
What are the products and reactants of photosynthesis
H2O, CO2, and sunlight
O2 and C6H12O6
Genetic information, including instructions for protein synthesis and other functions, are stored in what ORGANELLE?
Nucleus
If there are mutated non-functional proteins, where did the mutation occur?
Mutations occur in the DNA
What is the best part about Biology class?
Mr. Lillie!
From HIGH concentration to LOW concentration
or with the concentration gradient.
Cellular Respiration.
What is the purpose of mitosis for the human body?
Replace damaged or old cells, Growth.
How can you explain that a mutation occurs in a gene, but the gene functions normally?
Silent mutation
The mutation did not affect the amino acid sequence
What is the difference between a point mutation and a Frameshift mutation? Be sure to explain which is which.
Point mutation also called a substitution mutation is when a single nucleotide base is replaced with another.
A frameshift is when a nucleotide base is added or subtracted and shifts the entire sequence, affecting multiple codons.
what is the difference between active and passive transport.
Active uses ATP (energy)
What TYPE of energy does Photosynthesis produce?
Chemical (stored chemical energy)
what organelles is responsible for removing wastes from the cell, and recycling old proteins?
Lysosomes.
What are the three possible outcomes of mutation?
Missense (change in amino acid sequence)
Silent (no change)
Nonsense (codes for stop codon early)
CANDY QUESTION!!!!!!!!
What bird reaches the fastest maximum diving speed, while hunting prey?
Peregrine falcon.
What is homeostasis? and give one example of it.
Stable internal conditions.
Sweat, shivering, blood pressor, blood sugar and insulin,
CANDY QUESTION!!!!!!
During cellular respiration, explain why matter is not being created or destroyed?
Molecules are being rearranged, not destroyed. Net atoms are the same.
During cell division (mitosis) the duplicated chromosomes are called sister chromatids. These are identical copies of each other. Why do cells need sister chromatids, what is the purpose of having a second copy?
Allows cells to divide into genetically identical daughter cells.
What characteristic determines the proteins function?
Its Shape.
During transcription/translation proteins are synthesized. What determines a proteins shape or how it is folder?
The amino acid sequence.
Explain what the cell membrane is and what it does?
Cell membrane is made up of a bilayer of phospholipids that determine what enters and exits the cell. It is a barrier to keep what's in the cell, and to keep what's out of the cell, out.
Considering that mitochondria give us usable energy what cell type would you most likely find the most mitochondria?
Muscles.
(most specifically the heart muscles)
(Also due to more mitochondria and Myoglobin, as well as a few other factors, is why dark meat is dark)
***** CANDY QUESTION*****
After a fertilized egg (zygote) divides a few times, what is the process that occurs that allows identical cells in a developing organism to take on different structures and functions to meet the needs of that organism?”
Differentiation (they get assigned jobs)
Mutations can be the cause of genetic diseases like sickle cell anemia. When we talk about mutations, where do the mutations occur?
Name all the continents that you can find rattlesnakes in the wild?
North and South America
