Cellular Respiration

Question 1

What is cellular respiration?

Answer 1

chemical reaction by which organic molecules taken in as food are broken down to make energy available for a cell

Question 2

ATP (adenosine triphosphate)

Answer 2

a molecule that stores energy in the cells
made up of-
adenosine, three phosphate groups

Question 3

ADP (adenosine diphosphate)

Answer 3

the substance formed when the end phosphate group is removed from a molecule of atp

Question 4

Glycolysis

Answer 4

the breakdown of glucose to pyruvic acid, releases energy to form two molecules of ATP

Question 5

Anerobic and Aerobic respiration

Answer 5

Anerobic- production of lactic acid from glucose, respiration that does not require oxygen
Aerobic respiration- respiration that requires oxygen, occurs in mitochondria

Question 6

Oxygen dept and recovery

Answer 6

Recovery oxygen- extra oxygen needed to recover after an exercise
Oxygen dept-extra oxygen required to remove lactic acid produced during exercise

Question 7

Cellular respiration in the cell step 1 glycolosis

Answer 7

anerobic, in cytoplams
-1 glucose is converted into 2 pyruvate and 2nadh
-transported by active transport into mitochondria
pyruvate is oxidized and converted to 2 acetyl coa, carbon dioxide is released and 2nadh is produced

Question 8

Cellular respiration in the cell step 2 krebs cycle

Answer 8

aerobic, The 2 acetyl CoA enters the citric acid cycle/Krebs cycle
-carbon dioxide is released, 2 atp, 6 nadh and 2 fadh are produced

Question 9

Cellular respiration in the cell step 3 electron transport train

Answer 9

aerobicn, electrons are passed between molecules resulting in oxygen forming water and between 30-38 ATP
