B.4: Energy In Nutrients

Question 1

Cellular respiration / ATP

Answer 1

Metabolism of food molecules in cells in order to create ATP (adenosine triphosphate) - energy currency of cells

Question 2

Mitochondria

Answer 2

Powerhouse of the cell, organelle that is the “site” of energy production

Question 3

Areobic respiration

Answer 3

Respirtaion where tiny mitochondria have a highly folded inner membrane to allow mass production of ATP

Question 4

Anaerobic respiration

Answer 4

Respiration with the lack if mitochindria, meaning ATP is produced more slowly

Question 5

Obligate aerobe

Answer 5

Requires oxygen to perform cellular reapiration

Question 6

Obligate anaerobe

Answer 6

Requires an oxygen-free environment

because oxygen is lethal to them. Performs fermentation instead of cellular respiration

Question 7

Facultative anaerobe

Answer 7

Organisms that can switch between cellular respiration and fermentation, depending on environmental conditions

Question 8

Fermentation

Answer 8

Cellular respiration occuring in the absence of oxygen
