DNA replication: DNA nucleotides build new copies of both strands of DNA. (Circled words: Tonicity, cell cycle) Aerobic pathways: ones that require input of oxygen (Two main sections are circled) Cellular cytosol ↓ Glycolysis Mitochondrion ↓ pyruvate processing citric acid cycle electron transport chain Ch 4 Glycolysis → pyruvate → Acetyl CoA ↓ citric acid cycle ↓ electron transport chain Potential energy Potential energy: Fat stores the extra calories that we consume Protons & neutrons are located within the nucleus Amino acid → most basic unit, i.e. monomer, of proteins Active transport uses ATP to move substances up their concentration gradient but passive transport requires no cellular use of energy. During anaphase, chromosomes begin to separate Cell membrane → phospholipid bilayer with proteins A person is dehydrated → person's blood plasma would become hypertonic, causing the red blood cells to lose water & shrink Nucleotides & Nucleic Acids Nucleotides base + sugar + phosphate aid cell to cell communication in capture & transfer energy in high energy electrons or phosphate bonds "ATP" form DNA + RNA Nucleic acids - functions in information storage & transmission Atomic number → usually the number of electrons = number of protons [Diagram of a Bohr model atom with a nucleus and concentric electron shells containing 2, 8, and 32 electrons respectively.] 1 gram x (1/1000) = 1 gram x (1 / (10x10x10)) 1 gram x 1/10³ = 1 gram x 10⁻³ 1 miligram = 1 gram x 10⁻³ Molarity 1L = 1000g 1 Da = 1 g/mol M = molecular weight How many grams of CaCl₂ (m.w. 110 Da) do you need to make of a 1M solution 300mL 1M = x / 0.3L molar mass / molar weight = 110 Da 1M = X / .3L 300mL -> L x 10⁻³ 1M = x / 0.3L 110 = x / 0.3L 0.3 * 110 = x / 0.3L * 0.3 33 = x (Circled: 33 grams)
