Cellular Resp 1. Intro to cellular resp and ATP, includes mitrochondrioa and steps

Question 1

Cellular Respiration
-deffinition
-occurs in what

Answer 1

-controlled realease of energy from organic compounds to form ATP
-cells of all organisms (plants and bacteria too)

Question 2

What is ATP used for (4)

Answer 2

-active transport
-movement of cilia and flagella
-muscle contraction
-synthesizing compounds

Question 3

How do we use ATP energy
Breaking the bond realses _____ to ______ _______ _______. ______molecules are more ______ and more likley to react (activiating the molecule) Coupling the _______/________ hydrolysis of ATP with a reaction that is ________/______ will make it _______

Answer 3

-energy to power chemical rxns
-phosphorylated
-unstable
-exergonic/exothermic
-endergonic/endothermic
-spontaneous

Question 4

Aerobic Cellular Respiration
-balance reaction
-Glucose is ________
-Most ATP is produced through what chain reactions

Answer 4

C6H12O6 + 36P(ion)+36ADP+6O2 produces 6COS + 6H2O +36ATP
-glucose is catabloyzed in many steps through glycolysis and the Kerbs cycle
-most ATP is produced through a related chain of rxns called oxidativee phosphorylation

Question 5

Parts of Mitochondrion
-how many membranes, connected?
-inner membrane ____ to form what
-space between membranes is _____
-centre fluisd is called _____
-what ribosomes, and what DNA

Answer 5

-2 membranes, not connected
-inner membrane folds to form cristae
-space between is called intermembrane space
-fluid is called matrix
-70s ribosomes and cirrcular peice of naked DNA

Question 6

Explain the function
-Cristae
-Intermembrane space
-fluid matrix

Answer 6

-highly folded inner membrane, large surface area for many electron transport chains and proton pores
-small volume so protons will accumulate here with high concentration
-contains enzymes and intermediates for Krebs cycle

Question 7

Steps of Aerobic cellular respiration

Answer 7

1. glycolysis
2. Krebs cycle (including link rxn)
3. oxidative phosphorylation (Electron transport chain and chemiosmosis): oxidation/reduction (redox) rxns are used through cellular resp to strip energy from glucose

Question 8

Oxidation/ Reduction (Redox)
-Oxidation=
-Reduction=
-oxidizing agent=
-reducing agent=
-what happens when electron is transferred

Answer 8

-loss of electrons/hydrogen
-gain of electrons/hydrogen
-electron acceptor
-electron donor
-some energy is released and harnessed to do work
