Macromolecules
The reaction that links monomers into polymers by forming covalent bonds and releasing water.
What is dehydration synthesis?
This organelle is known as the “powerhouse of the cell.”
What is the mitochondrion?
Where does Glycolysis occur?
What is the cytoplasm?
Which of Mendel’s laws states that alleles for different genes separate independently during gamete formation?
What is the Law of Independent Assortment?
The lobe of the brain responsible for vision.
What is the occipital lobe?
When a protein loses its shape due to heat or changes in pH, it undergoes this process, often resulting in loss of function.
What is denaturation?
These structures allow plant cells to connect and share cytoplasm.
What are plasmodesmata?
What is the final electron acceptor in the Electron Transport Chain?
What is oxygen?
Two heterozygous pea plants (Yy) are crossed. What fraction of their offspring will show the recessive phenotype?
What is 25%?
The vascular tissue that conducts water and minerals.
What is xylem?
The lipid molecule with a four-ring carbon structure that serves as a precursor for hormones like testosterone and estrogen.
What is cholesterol?
The internal “9+2” arrangement of microtubules is found in these structures.
What are cilia and flagella?
What molecule enters the bridge reaction?
What is pyruvate?
A red flower (RR) crossed with a white flower (rr) produces pink offspring (Rr). What inheritance pattern does this show, and what would the offspring look like if codominance were at play instead? (MUST ANSWER BOTH PARTS)
What is incomplete dominance; under codominance, offspring would show both red and white patches.
The valve that prevents backflow of blood from the right ventricle to the right atrium.
What is the tricuspid valve?
This structural polysaccharide found in fungal cell walls and arthropod exoskeletons is similar to cellulose but includes nitrogen.
What is chitin?
This model describes the cell membrane as a dynamic mix of lipids and proteins.
What is the fluid mosaic model?
What are the three stages of the Calvin cycle, and what molecule is cycled throughout it?
What are Carbon Fixation, Reduction, and Regeneration, and RuBP?
In the 18th century, a young boy suffered from a skin condition that included thickening of the skin and the formation of loose spines that were periodically sloughed off. This “porcupine man” married and had six sons, all of whom had the same condition. He also had several daughters, all of whom were unaffected. What might you theorize about the mode of transmittance?
What is Y-Chromosome inheritance?
The multicellular diploid stage in alternation of generations, which produces haploid spores through meiosis.
What is the sporophyte?
What kind of glycosidic linkage connects amylopectin during branches?
What is an α1-6 linkage?
The basal body of a cilium or flagellum is structurally identical to this organelle.
What is a centriole?
What type of photosynthesis do cacti do?
What is CAM photosynthesis?
A couple comes to a genetic counselor concerned about their chances of having a baby with Tay Sachs disease. The husband had a sibling die of the disease, which is inherited as a autosomal recessive trait. What are the chances that he is a carrier?
What is ⅔?
(Reasoning: His parents’ children had a 25% of having an affected child, a 50% chance of having a carrier and a 25% non carrier. Since the husband didn't die of Tay Sachs, he is in one of the latter two categories, which should be produced in a 2:1 ratio.)
In angiosperms, the triploid tissue formed during double fertilization that nourishes the developing embryo.
What is an endosperm?
