Biology Quiz 6

TermDefinition
Chromosomes Human body cell has 46 of them
Erwin Chargaff Discovered relationships between DNA bases
Karyotype Organization of Chromosomes - size - centromere - Banding pattern
Diploid ( 2n ) Cells having two of each type of chromosome characteristic of. the species
Anaerobic No oxygen needed ( O2 )
Double Helix A-T and G-C ( Chargaff's Rule )
Maurice Wilkins Experimental Evidence of DNA structure
Johannes Mischer 1st described DNA Protein Complex
Rosalind Franklin Discovered structure of DNA by X-ray crystallography
8 Characteristics of DNA Right-handed double helix Sugar PO^4 Purines ( A6 ) Adanine has 2 hydrogen bonds to Thidine Each turn = 6 base pairs ( IUbp ) 2 surface grooves antiparallel 5 prime to 3 prime, 3 prime to 8 prime Semiconservative Machanism
Fermentation Anaerobic pathways that break down glucose molecules
Glycolysis occurs in cytoplasm 10 steps ATP --> NADH pyruvate is broken down in aerobic respiration Acetyle- COA forms --> citric acid cycle --> ETC
4 DNA Nucleotide) Adenine ( A ) Guanine ( G ) Cytosine ( C ) Thymine ( T )
Frederick Griiffith Discovered bacteria contains a transforming substance
Aerobic Need Oxygen ( O2 )
How do cells used stored Energy? transferring it to other molecules
James Watson + Francis Chick Built the first accurate model of a DNA molecule
Aerobic Respiration ( 36 ATP ) 1. Glycolysis 2. Krebb's Cycle 3. Electron transport Train ( ETC )
Lactate Fermentation Anaerobic pathway that converts pyruvate to lactate + produces ATP
Aerobic Respiration Equation C6H12O6 ( Glucose ) + O2 ( Oxygen) --> CO2 (Carbon Dioxide ) -->H20 (water ) + 36 ATP
Krebbs Cycle - 8 steps - Creates NADH, FADH, + ATP - Happens in Mitochondria
Electron Transfer Train ( ETC ) - Happens in mitchondria - Takes NADH from 2 previous steps+ FADH2 - ETC moves through protein complexes -Chemosmosis

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
