AP BIO - cell energy

QuestionAnswer
NADH vs NADPH NADPH is in photosynthesis and NADH is used in everything else
reduction gain of electrons, release energy
oxidation loss of electrons or H's
photosynthesis location chloroplast
light-dependent reactions (photosynthesis) 1. chlorophyll is in the thylakoid in photosystem 2 and is excited by photon, so loses an e- that goes to e- acceptor 2. cholorphyll needs e- and takes from water so its broken up and oxygen is released as waste 3. use energy of e- to pump H+ across thy
chemiosmosis Process by which a Hydrogen pump pumps protons into the thylakoid membrane. H+ passively flows through the ATP synthase which leads to the creation of ATP.
Calvin cycle (light-independent reactions of photosynthesis) 1. ATP and NADPH go to stroma and make glucose bonds 2. CO2 enters and binds with RUBP, which makes a 6-carbon molecule that's broken by enzyme called rubisco into 2 3-carbon molecules, reduced to form G3P 3. Some of the G3P leaves and create glucose a
how are NADPH and ATP made? ATP was phosphorylated and NADPH was reduced with H
cellular respiration equation C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP
glycolysis (cellular respiration) takes place in cytoplasm (anaerobic), energy investment of 2 ATP to break glucose equation: glucose + 2 NADP --> 2 pyruvate + 2 NADPH + 2ATP
pyruvate oxidation (cellular respiration) equation 2 pyruvate + 2 NAD --> 4 CO2 + 6 NADH + 2 ATP + 2 FADH2.
kreb's cycle/citric acid cycle (cellular respiration) occurs in the mitochondrial matrix, for every one glucose the cycle goes twice, start with oxaloacetate which binds to acetyl CoE A which makes citric acid, release CO2 as waste and NAD + FAD capture energy and are reduced to NADH and FADH2, end back with
electron transport chain (cellular respiration) occurs in inner membrane in mitochondria, oxidative phosphorylation oxidizes NADH and FADH2, pump the H across the inner membrane in mitochondria to create proton gradient, chemiosmosis (H+ flows back through ATP synthase to make 32 ATP), O2 is final elec
lactic acid fermentation glycolisis still occurs because anerobic so produces pyruvate and NAD+ then since no O2, NAD+ is recycled to continue glycolisis and create lactic acid
alcohol fermentation glycolisis occurs and then pyruvate is broken up and becomes alcohol and CO2 which reduces to NAD+
calvin cycle location stroma of chloroplast
glycolysis location cytoplasm
pyruvate oxidation location mitochondrial matrix
kreb's cycle location mitochodrial matrix
ETC location inner membrane of mitochondria

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.
