Flashcards in Text Chapter 4: Cellular Respiration Deck (15):
1

Glycolysis (inputs and outputs)

Inputs- 2 ATP, 2NAD+
Outputs- 4 ATP, 2NADH

2

Kreb's Cycle (inputs and outputs)

Inputs- 2ADP, 6NAD+, 2FAD
Outputs- 2 ATP, 4CO2, 6NADH, 2FADH2

3

Electron Transport Chain (inputs and outputs)

inputs- 2NADH, 2NADH, 6NADH, 2FADH2, O2
outputs- water, 32 ATP

4

Structure of Mitochondrion and Regions involved in Cellular Respiration

Inner Membrane: Electron Transport Chain
Matrix: Krebs Cycle, Acetyl-CoA formation
Intermembrane Space: H+ ions accumulate
Crista= folds

5

Overall Gain of ATP from the Complete Breakdown of Glucose

36 ATP; 2 from glycolysis, 2 from Kreb's cycle, 32 from the chain

6

Area where most ATP is Produced

electron transport chain, inner membrane of mitochondria, 32 ATP

7

Electron Carriers involved in the Breakdown of Glucose

NAD+, FAD

8

Chemiosmosis in Mitochondria

diffusion of protons through channel in ATP synthase gives energy for ATP synthesis

9

Fermentation v. Cellular Respiration

fermentation generates NAD+ to allow glycolysis to continue

10

Where Energy-Rich Molecules Enter the Glucose Pathway

in the cytoplasm under anaerobic conditions (no oxygen needed)

11

Factors that Influence Metabolic Rate

temperature

12

Cellular Respiration v. Photosynthesis

Cellular respiration starts with glucose and ends with CO2 and water, occurs in the inner membrane of the mitochondria
Photosynthesis starts with CO2, ends with glucose, occurs in chloroplast

13

Where can Lactic Acid be Converted back to Pyruvate

liver

14

When Brain cells use Glucose for Energy

in the presence and absence of carbohydrates

15

When Brain cells use Proteins for Energy

in the absence of carbohydrates
