Question 21

Draw the Mitochondria and the three stages of cellular respiration

Answer 21

Class one Study guide

Question 22

CR Stage 1

Answer 22

Glycosis (cytosol)

Question 23

CR Stage 2

Answer 23

Pyruvate Oxidation and Citric Acid Cycle (matrix)

Question 24

CR Stage 3

Answer 24

Oxidative Phosphorylation (inner membrane)

Question 25

Cells Capture Energy from Electons “Falling” from organic fuels to oxygen

Answer 25

Glucose is oxidized - falling electrons accepted by coenzyme, NAD+ reduced to NADH NADH delivers electrons to string of electron carrier molecules. Energy released from electrons used in making of ATP At end of ETC osygen accepts 2e-, picks up 2 H+ ,reduced to water

Question 26

Photosynthesis

Answer 26

green plants and other organisms transform light energy into chemical energy

Question 27

Cellular Respiration

Answer 27

organisms use oxygen to break down food molecules,

getting chemical energy for cell functions

Question 28

Breathing

Answer 28

process of respiration, air is inhaled into lungs due to muscle contraction then exhaled due to muscle relaxation.

Question 29

Redox Reactions

Answer 29

reactions that involve the transfer of electrons from one species to another

Answer 36

splits glucose into two pyruvate molecules

Question 37

Pyruvate Oxidation

Answer 37

oxidation of pyruvate

creating acetyl CoA

Question 38

Citric Acid Cycle

Answer 38

metabolic pathway connecting carbohydrate, fat, and protein

reactions carried out by eight enzymes that completely oxidize acetate

Question 39

Oxidative Phosphryalation

Answer 39

harnessing reduction of oxygen

generating high energy phosphate bonds

Question 40

Chesmiosomosis

Electron Transport Chain

Answer 40

movement of hydrogen ions across the membrane through ATP synthase

electrons pass from one molecule to another, energy released in electron transfers form an electrochemical gradient.
