|---|---|---|---|---|---|
| Chemical composition of an enzyme (protein, sugar, lipid, etc) | show 🗑
|
||||
| Potential energy | show 🗑
|
||||
| show | total amount of energy in universe constant and unchanging. "energy can be transferred and transformed, but it cannot be created or destroyed.
🗑
|
||||
| show | Covalent bonds
🗑
|
||||
| show | is the use of an exergonic process to drive an endergonic one. "exergonic energy to endergonic reactions is a cycle"
🗑
|
||||
| What phosphorylation BASICALLY means | show 🗑
|
||||
| Energy Activation starting chemical reactions | show 🗑
|
||||
| show | 1. Chemical Work- pushing of endergonic reactions. phosphorylation to endergonic.
2. Mechanical Work-transfer of phosphate group to drive muscle contraction.
3. Transport Work- phosphorylating membrane proteins to drive muscle contraction.
🗑
|
||||
| show | Enzymes are specific to substrate, it has active site. substrate binds with active site in order to start reaction. "if substrate does not fit, reaction will not occur." Ex: Amylase enzyme is specific to starch; it will not break down protein.
🗑
|
||||
| High temperature effects on enzyme and substrate | show 🗑
|
||||
| pH effects on enzyme and substrate | show 🗑
|
||||
| Enzymes as inhibitors (competitive, noncompetitive) How do they work as competitive, and how do they work as noncompetitive. Think NSAIDs. | show 🗑
|
||||
| show | is the regulations of metabolism.
🗑
|
||||
| How shape affects function | show 🗑
|
||||
| RNA ribozymes. What is it made out of. | show 🗑
|
||||
| show | stops the reduction reaction, cannot generate ATP, or stops ATP synthesis which results in death.
🗑
|
||||
| Membranes are: (hydrophilic, hydrophobic, amphipathic?) | show 🗑
|
||||
| Purpose of transmembrane proteins | show 🗑
|
||||
| What composes cell surface markers | show 🗑
|
||||
| Phospholipids and bilayers | show 🗑
|
||||
| Different proteins in lipid bilayer and what they do. What are they responsible for. | show 🗑
|
||||
| show | Molecules spreading out, uses energy to move.
🗑
|
||||
| Diffusion of CO2 and O2 | show 🗑
|
||||
| What ions maintain proper balance in a cell | show 🗑
|
||||
| Isotonic, hypertonic, hypotonic | show 🗑
|
||||
| Transport of large molecules into the cell | show 🗑
|
||||
| show | Receives and chooses what is coming into the cell.
🗑
|
||||
| Cellular respiration creates _________ for cell | show 🗑
|
||||
| show | Aerobically, long muscle contractions, used by slow fibers (mitochondria), produces ATP, CO2, and H2O
🗑
|
||||
| Use without O2 (in regards to cellular respiration) | show 🗑
|
||||
| Efficiency of ATP | show 🗑
|
||||
| show | They have to be paired with each other. it's a movement of electron from one molecule to another.
🗑
|
||||
| show | lose the electrons to become more positive
🗑
|
||||
| show | gains electrons
🗑
|
||||
| Purpose of NAD+ | show 🗑
|
||||
| Final electron acceptor | show 🗑
|
||||
| What is Glycolysis | show 🗑
|
||||
| show | cytoplasm
🗑
|
||||
| show | it breaks molecules of glucose into 2 pyruvate (3 carbon molecules)
🗑
|
||||
| show | Stage 2, occurs in the mitochondria, moves to stage 3 to make full use of energy.
🗑
|
||||
| show | From the cytoplasm to mitochondria
🗑
|
||||
| Generally how much ATP is produced during the citric acid cycle? | show 🗑
|
||||
| show | Know which processes are involved (gradient, hydrogen ions, osmosis?) - it has electron transport chain called chemiosmosis. as electrons are being "passed down" chain, H+ are released and move across mitochondria membrane.
🗑
|
||||
| show | as INTERMEDIATE" it occur in middle process. it becomes PRODUCT of step 1 to become REACTANT of step 2 to become product end. then step 2 become reactant of step 3
🗑
|
||||
| Coenzymes as transporters | show 🗑
|
||||
| show | To make large amounts of energy within the cells. more efficient ways to make ATP.
🗑
|
||||
| show | Pyruvate
🗑
|
||||
| show | CO2 and ethanol
🗑
|
||||
| Photosynthesis taking ________ molecules and what converts to | show 🗑
|
||||
| What plants split | show 🗑
|
||||
| show | Wavelengths are distance between successive crests (measured in nm), determine amount of energy the ray contains (blue light has shortest wavelengths and highest energy)
🗑
|
||||
| Light intensity | show 🗑
|
||||
| Importance of pigments | show 🗑
|
||||
| show | Red light alone: promotes little photosynthesis.
Red light Together: is more effective because there is more photosynthesis (more wavelengths)
🗑
|
||||
| show | Photosystem I, has 2 options for pathways (cyclic and non-cyclic)
🗑
|
||||
| show | Photosystem II, has one pathways
🗑
|
||||
| show | O2
🗑
|
||||
| Where cyclic phosphorylation occurs. What part of the chloroplast does it occur. | show 🗑
|
||||
| Why noncyclic phosphorylation is important | show 🗑
|
||||
| Calvin cycle, what enters and what exits (basic overall idea) | show 🗑
|
||||
| Adaptations of plants to conserve H2O, CO2, photons | show 🗑
|
||||
| show | CAM means crassulacean acid metabolism. Desert plants, only open stomata to capture CO2 at night only so H2O loss is minimum. Stores CO2 to use during the day
🗑
|
||||
| Destruction of CFCs | show 🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
