2.1 Metabolite/Water

QuestionAnswer
molecular biology explains living processes with references to chemical processes involved
most common elements hydrogen, oxygen, nitrogen, carbon
covalent bonds of carbon 4
covalent bond sharing a pair of valence electron
carbon based compounds carbohydrates, lipids, proteins, nucleic acids
Friedrich Wohler disproved vitalism by taking inorganic molecules and synthesizing them into an organic molecule
metabolism all the enzyme-catalysed reactions in cells organisms
anabolism synthesis of complex molecules from simpler molecules
chemical reaction of anabolism condensation reaction
catabolism breakdown of complex molecules into simpler molecules
chemical reaction of catabolism hydrolysis reaction
bonds between hydrogen and oxygen in a water molecule covalent
polarity of water slightly negative area around the oxygen versus slightly positive area around the hydrogens
bond between molecules of water hydrogen
cause of hydrogen bonding dipolarity
unique properties of water cohesive, adhesive, thermal, solvent
cohesive benefit surface tension
adhesive benefit capillary action in small spaces
thermal benefit high heat of vaporization
solvent benefit good transport medium
solubility of glucose, polar amino acids, and sodium chloride soluble
solubility of oxygen and non-polar amino acids soluble at low concentrations
solubility of fats and cholesterol soluble with assistance
methane 1. no hydrogen bonds 2. low boiling point 3. low freezing point 4. changes phases easily 5. not a solvent
water 1. hydrogen bonds 2. high boiling point 3. high freezing point 4. stable phases 5. good solvent

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.
