3.7 & 8.1 Cell Respiration

Question 1

Oxidation involves…, Reduction involves…

Answer 1

Oxidation: loss of electrons, frequently involvesgaining oxygen or losing hydrogen

Reduction: electrons, usually involves loss of oxygen or gain of hydrogen

Question 2

Outline the process of glycolysis including phosphorylation, lysis, oxidation and ATP formation

Answer 2

Do it

Question 3

Draw and label dark I’m sure the structure from mitochondria soon electron micrograph

Answer 3

Include outer membrane intermediate space Chris day and matrix

Question 4

Explain aerobic respiration, including the link reaction, the Krebs cycle, the role of NADH plus H plus, the electron transport chain and the role of oxygen

Answer 4

Call link reaction and crab cycle happen in the matrix, C2 is called acetylCoA, Laurent two times therefore net products are two ATP, six NADH, 2 FADH, 4 CO2

Electron transport chain H plus and two electrons are just by mad, move down to the cytochrome because it has a higher electronegativity as they move down they really small energy is ATP.

Role of oxygen, final except her because very high electronegativity when combined with electrons so surroundinghydrogen ions which produces H2O this is referred to as water of metabolism

Question 5

Explain oxidative phosphorlaytion in terms of chemiosmosis

Answer 5

Do it

Question 6

Explain the relationship between the structure of the mitochondria and its function

Answer 6

Outer membrane: separates the contents of the mitochondria from the rest of the cell. Matrix: internal site also like area which has enzymes and pH for link reaction and Krebs cycle. Chris day: tubular region surrounded by membranes increase our surface area for oxidative phosphorylation. And a membrane: contains carriers of the electron transport chain and ATP synthase For chemioosmosis
Inter-membrane space: reservoir for hydrogen ions, allows concentration gradient to form for chemiosmosis

Question 7

Explaine that during anaerobics Osprey Shannon, pyruvate can be converted in the cytoplasm into lactate or ethanol and carbon dioxide is no further yelled at ATP

Answer 7

Anaerobic respiration is when our organisms are either ATP without the use of oxygen, also called fermentation, two pathways alcohol fermentation and then east or lactic acid fermentation in animals

Alcohol for me Shane: like a cop glycolysis splitting glucose to par you pyruvate then Pat pyruvate is converted into ethanol, carbon is lost into the conversion into a CO2 molecule, both ethanol and see you two are the waste released

Question 8

Define cell respiration

Answer 8

Controlled release of energy from organic compounds in cell to produce ATP, commonly done through variety of biochemical pathways that can be used to metabolize glucose
