Aerobic respiration

Question 1

glycolysis

Answer 1

-takes place in cytoplasm
-glucose input – 6 C – carbon-containing input
- pyruvate output – 3 C - carbon-containing output
-2 ATP input and 2 NAD+ - energy input
-4 ATP and 2 NADH output – energy output
-occurs in 10 steps

Question 2

pyruvate oxidation

Answer 2

-occurs in the mitochondrial matrix
-pyruvate input
-acetyl CoA, 2 NADH and CO2 output
-acetyl CoA goes into the citric acid cycle

Question 3

citric acid cycle

Answer 3

-occurs in mitochondrial matrix
-Acetyl CoA
-CO2 (2)
-GDP and NAD+ and FAD input
GTP (2) and NADH (6) and FADH (2) output

Question 4

chemiosmosis

Answer 4

-occurs in the mitochondrial matrix
-NADH and FADH - input
O2, ATP, and Pi – input
-H2O, NAD+, FAD+ - output
-28 ATP – output

Question 5

oxidative phosphorylation

Answer 5

-the reason why our cells need oxygen
-ATP is synthesized by reoxidation of electron carriers in the presence of O2
-two components: electron transport and chemiosmosis
-occurs in the mitochondrial inner membrane
