chapter 5 questions

QuestionAnswer
what is oxidation reaction? oxidation- loses electrons (leo)
what is reduction reaction? reduction- gains electrons (ger)
describe the oxidation-reduction reaction? if an electron is lost it has to be gained by another, reducing its electrical charge CO2 + H2= CO + H2O electron carriers; NAD+, NADP+, and FAD
What is oxidative phosphorylation? energy released from the transfer of electrons (oxidation) from one compound to another (reduction) is used to generate ATP in the electron transport chain
What is photo-phosphorylation? light causes chlorophyll to give up electrons. Energy is released from transfer of electrons (oxidation) of chlorophyll through a system of carrier molecules used to generate ATP
What are the major facts of Glycolosis? occurs in he cytosol (anaerobic) involves splitting of 6 carbon glucose into two 3 carbon sugar molecules net gain 2 ATP 2 pyruvic acid produced 2 NADH produced
name the steps to glycolosis? 2 ATP are used- glucose is split to form 2 glucose-3phosphate- 2 glucose-3phosphate oxidized to 2 pyruvic acid= 4 ATP produced and 2 NADH produced
Major steps of CAC (Kreb cycle)? for each original molecule of glucose that is utilized in carbohydrate catabolism the CAC results in oxidation of acetyl CoA produces 2 ATP, 2 FADH, 6 NADH, 4 CO2 it occurs in he cytosol of prokaryote and in mitochondria of eukaryote
What are the major steps of the Electron Transport Chain? carrier molecules; FMN, ubiquinones or coenzyme Q, cytochromes, metal containing proteins Happens through chemiosis to pump protons across a membrane located in the cristae of eukaryotic and cytoplasmic membrane of prokaryotic
what process gives the most production of ATP molecules? The electron transport chain with 34 ATP from molecule of glucose
What are the alternative pathways to glycolosis? pentose phosphate pathway- uses pentose's and NADPH, operates with glycolosis enzymes Enter-doudoroff pathway- produce NADPH and ATP, does not involve any of the enzymes of glycolosis
What is the general pathway of fermentation and what are the final electron receptors? metabolic pathways that are metabolic reactions that oxidize NADH to NAD+ while reducing cellular organic molecules. It allows ATP production to continue in the absence of cellular respiration. Final electron acceptors are organic molecules
what are the major events of photosynthesis? light dependent- depend on the light light independent reactions- synthesize glucose from Co2 and water
what is the difference between oxygenic and anoxygenic? oxygenic- derive electrons from the dissociation of H2O anoxygenic- gets electrons from inorganic compounds resulting in non oxygen waste such as sulfur
What is a chemotrophs and chemoautotrophs? aquires energy from redox reactions involving organic and inorganic chemicals to survive chemhetetrophs- animals, fungi, protozoa
What is phototrophs? use light for energy source photoautotropphs- plants, some protozoa, and algae

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.
