Cellular Respiration

Question 1

calorie

Answer 1

• the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius

Question 2

cellular respiration

Answer 2

• the process of energy conversion that releases energy from food in the process of oxygen

Question 3

aerobic

Answer 3

• (“in air”) pathways of cellular respiration that require oxygen

Question 4

anaerobic

Answer 4

• (“without air”) pathways of cellular respiration that do not directly require oxygen, nor do they rely on an oxygen - requiring process to run

Question 5

glycolsis

Answer 5

• (“sugar breaking”) the first set of reactions in cellular respiration
• 1 molecule of glucose, a 6-carbon compound, is transformed into 2 molecules of the 3-carbon compound pyruvic acid

Question 6

NAD+

Answer 6

• (nicotinamide adenine dinucleotide) an electron carrier

Question 7

Krebs cycle

Answer 7

• the second stage of cellular respiration in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions

Question 8

matrix

Answer 8

• the innermost compartment of the mitochondrion and the site of the Krebs cycle reactions

Question 9

fermantation

Answer 9

• in the absence of oxygen, this releases energy from food molecules by producing ATP
