Biochemistry
What kind of molecule can pass though a Lipid Bilayer passively?
Small, Nonpolar
Results of Mitosis and Meiosis
Mitosis- 2 Identical (Diploid) Daughter Cells-Somatic
Meiosis- 4 Genetically Diverse (Haploid) Cells- Gametes. Oogenesis produces 1 egg and 3 polar Bodies
2 Membrane organelles that are known to have a double membrane that maintains an electron transport chain, as well as provides evidence for the endosymbiotic theory.
Mitochondria and Chloroplasts
Archea and Bacteria are both Prokaryotes or Eukaryotes?
Prokaryotes
Active vs. Passive Transport
Passive will happen with a gradient, and requires no energy. Active Transport needs energy (ATP Coupling) and goes against a gradient
Two chromosomes in a pair – normally one inherited from the mother and one from the father
Homologous Chromosomes
What is the Role of DNA
Genetic Code- Allows for production of Proteins
Differences Between Prokaryotes and Eukaryotes
Prokaryotes have no Nucleus, No Membrane Bound Organelles, and are simpler. Eukaryotes have nucleus, membrane bound organelles, and are more complex.
ATP is commonly used as an energy source because...
Easy to transfer energy, High energy bonds, Ancestors used forms similar
Diversity occurs through recombination and crossing Over, which phase does this take place in?
Prophase 1
A Messenger Ligand reaches a cell and is received by one of its receptor proteins, When the signaling molecule binds the receptor it changes the receptor protein in some way.
Reception of a cellular signal
What is Carbon Dioxide's role in Photosynthesis?
Raw material, Provides a source of Carbon,
When an enzyme is denatured, what happens?
The physical structure is changed, sometimes irreversibly. Can occur at the secondary, tertiary or quaternary structures
What are 2 Differences between Meiosis and Mitosis?

A change in the receptor protein change initiates this process, a pathway of several steps. Each relay molecule in the pathway changes the next molecule in the pathway.
Transduction
Body existing at balance (preferred internal conditions), main goal of the body is to maintain this
Homeostasis
What kind of molecules are hydrophobic? Which kind are hydrophilic?
Hydrophobic-Nonpolar, Hydrophilic-Polar
What are 2 similarities between Mitosis and Meiosis?

Final step in Cell signaling, the signal triggers a specific cellular response
