Final Flashcards
Isotope
Missing or extra number of neutrons. Protons and electrons are the same.
Archaea
Prokaryotes, have no cell nucleus or any other membrane-bound organelles in their cells. Sister group Eukarya
Prokaryotes
Simplest cell, no membrane-bound organelles.
Eukaroytes
Have membrane-bound organelles, especially the nucleus, which contains the genetic material, and is enclosed by the nuclear envelope
Sister group of Archea
Eukarya
Peptide Bond
Covalent bond formed between two amino acid molecules
R group
Chemical group attached to the alpha carbon in an amino acid
Mass units
Protons + neutrons
Glucose
Monomer
Amino Acid
Monomer of broken down protein
Carrier molecules
Structures that stick, carry a molecule to change the charge
pH scale
Increase H+ –> more acidic
Increase OH- –> more basic
Salmonella, E coli
Represent first bacteria
Starch
Made up of glucose
Molecule to diffuse in portal
Molecule must dissolve in water, can only dissolve in water if it’s polar. If non-polar, has to dissolve with charges
Active transport
- Facilitated transport + added energy 2. Changing shape of protein 3. Driving movement of a molecule
Suffix -some
Unit
Insulin
Polypeptide
rRNA
Looks at sequence of nitrogenous bases in mRNA
Peptidoglycans
Amino acid —covalent bond— sugar
Mesosomes
Increase surface area, add more protein and enzymes
Na+/K+
K+ into cell, Na+ out of cell
Protein Synthesis
DNA into mRNA, gets read by ribosome, takes in 3 sets of nucleotide. Nucelotide goes into rRNA three at a time and matches the three with tRNA
Endoplasmic reticulum
Factory for protein synthesis (contains ribosomes + mRNA)
IKI
Starch indicator
Lumen
Inside of tube
Gene
Gives right enzyme to produce in protein synthesis
Calvin Cycle
Synthesis of sugar in chloroplast, c-c-c-c
Protists
Amoeba, paramecium, euglema
Amoeba
Responsiveness to external enviornment
Paramecium
Cell movement
Euglena
Chloroplast
-cytes
Stem cells
Ammalids
Earthworm
Ectoderm
Outside layer (connective)
Mesoderm
Middle layer, maintaining prebiotic soup (muscle (contractive) nervous)
Endoderm
Inner layer (epithelial)
Phosphase
Breaks down nucleus
Metaphase
Line up chromosomes in the equator of cells
Anaphase
Chromosomes pulled to opposite poles
Telophase
Chromosomes decondense, nuclear envelope is formed
Veins
Carry to heart
Arteries
Carry out the heart
Path of red blood cells
Red blood cells enter the right side, travel up pulmonary artery to lung to pick up oxygen. Travel to left side of heart, heart pumps rdc rich in oxygen to body. Oxygen is dropped of, Carbon dioxide is picked up. Rbc takes CO2 to right side of heart. Heart pumps rbc to lungs where CO2 is dropped of and O2 is picked up.
Membrane featuring lipids
Saturated fatty acid cause it to be more fluid
Unsaturated fatty acid cause it to be less fluid
Hypertonic
Concentration with higher solute concentration and less water concentration. Water flows out of cell, cell shrinks.
Hypotonic
Lower solute concentration and more water concentration. Water into cell, cell bursts.
Isotonic
Solution in which water molecule and solute molecule are equal in concentration. Equillibrium
Competitive inhibitior
Binds to active site of enzyme
Oxidize
Loses electrons, decrease potential energy
Reduced
Gains electrons, increase potential energy
Krebs Cycle (citric acid cycle)
Occurs in mitochondria, creates carbon molecules
Glycolysis
Glucose molecule broken down to two pyruvate. Each pyruvate is converted to acetyl-CoA
Chloroplasts
Capture light energy from the sun to produce energy stored in ATP and NADPH through a process called photosynthesis
Carbon fixation
Inorganic carbon (CO2) bonds with organic compound
Actin
Protein binding protein used to strengthen tight junctions
Which of the following statements about NAD+ is true?
NAD+ is reduced to NADH during glycolysis, pyruvate oxidation, and the citric acid cycle
Photosystem II
Takes electrons from water
Tubulin
Does not require ATP to function
Hydrolysis
Reaction involving the breaking of a bond in a molecule using water. Increase entropy
-ose
Amount of carbon atoms, ex. hexose = 6 carbon atoms
Active transport
Passing through cell membrane from high concentration to low
Smooth E.R
Synthesize lipids
Cytoskeleton
Made up of microtubules and microfilaments
