Chemistry of life
This type of bond forms between water molecules due to partial charges.
hydrogen bond
This organelle is responsible for ATP production in eukaryotic cells.
What is the mitochondrion?
The process plants use to convert light energy into chemical energy.
What is photosynthesis?
This type of signaling occurs between neighboring cells.
What is paracrine signaling?
This term describes two identical alleles.
What is homozygous?
The property of water that allows it to resist temperature change.
high specific heat
The process by which water moves across a selectively permeable membrane.
What is osmosis?
The molecule that acts as the main energy currency of the cell.
What is ATP?
The phase of the cell cycle where DNA replication occurs.
What is S phase?
The law stating alleles separate during gamete formation.
What is the Law of Segregation?
This scale measures acidity based on hydrogen ion concentration.
pH scale
This structure modifies, sorts, and ships proteins.
What is the Golgi apparatus
This stage of cellular respiration produces the most ATP.
What is oxidative phosphorylation (electron transport chain)?
This protein regulates the cell cycle and can prevent cancer.
What is p53 (or tumor suppressor protein)?
The expected phenotypic ratio of a dihybrid cross between two heterozygous parents for both traits.
What is 9:3:3:1?
This type of fat has no double bonds and is typically solid at room temperature.
What are saturated fats
The type of transport that requires energy to move substances against a gradient
What is active transport?
Type of protein that speeds up reactions by lowering activation energy.
What is an enzyme?
The process by which a cell self-destructs in a controlled way.
What is apoptosis?
The inheritance pattern where heterozygotes show both traits.
What is codominance?
Building polymers from monomers requires this reaction.
What is dehydration synthesis (condensation)?
Blocking membrane proteins would most directly affect this process.
What is facilitated diffusion or active transport?
This molecule is the final electron acceptor in the electron transport chain.
What is oxygen?
This signaling pathway involves a ligand binding to a receptor causing a cascade.
What is a signal transduction pathway?
The probability of two heterozygous parents having a recessive offspring.
What is 25% (or 1/4)?
