cell resp

Question 1

what does chem energy provide energy for

Answer 1

• active transport
• cell movement cila and flagella
  -chromosmal movement
• muscle contraction
• synthesis of macromolecules

Question 2

what is atp high energy

Answer 2

because of phosphate negative charge

Question 3

what is oxidation

Answer 3

atom or molecule loses an electron (H) ]

Question 4

what is reduction

Answer 4

atom or molecule gains an electron (H) more energy
*when one molecule is oxidized another must be reduced

Question 5

in which form do compounds have more energy in

Answer 5

reduced form

Question 6

what happens to glucose and oxygen in cell resp

Answer 6

glucose oxidized
oxygen reduced

Question 7

what kind of reaction is cell resp

Answer 7

glucose breakdown is a oxidation-reduction reaction

Question 8

reaction with oxygen

Answer 8

areobic resp

Question 9

reaction wtihout oxygen

Answer 9

anaerobic resp

Question 10

3 main steps to cell resp

Answer 10

glycolysis
krebs cycle
electron transport chain

Question 11

redox reaction

Answer 11

during cell resp glucose is oxidized by losing electron while oxygen is reduced by gaining electron

Question 12

anaerobic cell resp and 2 stages

Answer 12

glucose is metabolism in the absence of oxygen produces 2 ATP molecules and ethonal or lactic acid
2 stages: glycosis and fermentation

Question 13

aerobic cell resp and 4 stages

Answer 13

glucose metabolism with oxygen produceds 36 ATP molecules CO2 and H2O
4 stages:
- glycosis
- pyruvate oxidation
- krebs cycle
- electron transport
- chemoisosis

Question 14

releasing energy through aerobic resp

Answer 14

series of enzyme-catalyzed reactions where electrons are transferred from glucose to oxygen to generate ATP

Question 15

releasing energy through anaerobic resp

Answer 15

series of reactions that do not use oxygen as electron acceptor
