These organelles, once free-living bacteria that were engulfed by early eukaryotes, now produce most of a cell's ATP through oxidative phosphorylation.
- Mitochondria
- Ribosomes
- Golgi apparatus
- Endoplasmic reticulum
In this phase of cell division, chromosomes line up along the middle of the cell, attached to spindle fibers at their centromeres.
- Prophase
- Metaphase
- Anaphase
- Telophase
This molecule carries amino acids to the ribosome during protein synthesis, matching its anticodon to messenger RNA codons.
- Messenger RNA
- Ribosomal RNA
- Transfer RNA
- Small nuclear RNA
Water molecules moving across a selectively permeable membrane from areas of low solute concentration to high solute concentration describes this process.
- Osmosis
- Diffusion
- Active transport
- Facilitated diffusion
This nitrogen base pairs exclusively with adenine in DNA through two hydrogen bonds, following Chargaff's rules of base pairing.
- Guanine
- Thymine
- Cytosine
- Uracil
These tiny cellular structures read messenger RNA sequences and assemble amino acids into polypeptide chains during translation.
- Lysosomes
- Centrioles
- Nucleoli
- Ribosomes
This phase of cellular respiration occurs in the cytoplasm without oxygen and breaks glucose into two pyruvate molecules while producing a small net gain of ATP.
- Glycolysis
- Krebs cycle
- Electron transport chain
- Oxidative phosphorylation
The enzyme that unwinds the double helix and separates DNA strands during replication by breaking hydrogen bonds between base pairs is called this.
- DNA polymerase
- DNA ligase
- Helicase
- Primase
