Chemistry of Life
This subatomic particle has a negative charge.
What is an electron?
The movement of molecules from high concentration to low concentration.
What is passive transportation? Diffusion, facilitated diffusion, and osmosis.
The organelles where photosynthesis and respiration take place.
What is the chloroplast and mitochondria?
DNA replication occurs during this phase of interphase.
What is S phase?
When cell division results in 4 haploid, n cells
What is meiosis?
This bond forms when electrons are transferred from one atom to another.
What is an ionic bond?
Enzymes speed up reactions by lowering this.
What is the activation energy?
Glycolysis occurs in this part of the cell.
What is the cytoplasm?
A change in DNA sequence is called this.
What is a mutation?
This phase of Meiosis 1 is when crossing over occurs.
What is Prophase 1?
This weak attraction forms between partially charged molecules.
What is endocytosis?
This molecule is the main reactant of cellular respiration and product of photosynthesis.
What is glucose? C6H12O6
Sister chromatids separate during this phase.
What is anaphase?
The failure of chromosomes to separate properly is called this.
What is nondisjunction?
The building blocks of carbohydrates are these.
What are monosaccharides/glucose?
The diffusion of water across a semi-permeable membrane.
This type of cellular respiration does not require oxygen and only goes through glycolysis.
What is anaerobic respiration?
This gene promotes cell division.
What is the proto-oncogene?
Unlike mitosis, meiosis 1 separates these.
What are homologous chromosomes?
A macromolecule with only the elements C,H,O,N is probably this type of macromolecule.
What are polypeptides/proteins?
The cell membrane is primarily made of this type of molecule.
What is a phospholipid? (phospholipid bilayer)
This stage of cellular respiration produces the most ATP.
What is the electron transport chain?
The division of the cytoplasm following mitosis.
What is cytokinesis?
This process results in many possible chromosome combinations in gametes.
What is independent assortment?
