To produce energy from food you eat by breaking chemical bonds (#1)

What is the goal of cellular respiration?

10 pts Cellular Respiration

False – cellular respiration takes place in plants, animals, fungi, protists and most bacteria (#12)

True or False: Cellular respiration only takes place in plants

20 pts Cellular Respiration

Photosynthesis and cellular respiration are opposing processes. Reactants of one are products of the other, and vice versa.

(not on worksheet – on studyguide for final)

How are photosynthesis and cellular respiration related?

30 pts Cellular Respiration

6O2 + C6H12O6 6CO2 + 6H2O + Energy (not on worksheet – add it!)

What is the balanced equation for cellular respiration?

40 pts Cellular Respiration

Without the presence of oxygen (#10)

Glycolysis is anaerobic. What does anaerobic mean?

10 pts Glycolysis

Glycolysis occurs in the cytoplasm of the cell

(#8)

In what part of the cell does glycolysis occur?

20 pts Glycolysis

PYRUVIC ACID (#1 from 9.2)

What is the product of glycolysis?

30 pts Glycolysis

1. Glycolysis can produce ATP very fast if the cell’s energy needs suddenly increase

2. It can still supply energy when oxygen is not available (#5 from 9.2)

What are 2 advantages of glycolysis?

40 pts Glycolysis

The mitochondria – specifically the matrix, the innermost compartment (#7)

In what organelle does the Krebs cycle take place? And in what specific place in this organelle?

10 pts Krebs Cycle

The citric acid cycle (#7)

What is another name for the Krebs cycle?

20 pts Krebs Cycle

True (only glycolysis can occur in the absence of oxygen) (#9)

True or False: The Krebs cycle is aerobic (it requires oxygen)

30 pts Krebs Cycle

Pyruvic acid is the reactant (needed)

Through a series of reactions, citric acid is produced

(#2, #8)

What is the reactant (what is needed) for the Krebs cycle, and what is the product ?

40 pts Krebs Cycle

High-energy electrons convert ADP ATP

(#9)

What is the molecule needed for the electron transport chain to transform energy?

10 pts Electron Transport Chain

NAD+ (which is converted to NADH)

(#3)

What is the special electron carrier that takes high-energy electrons from glycolysis to the electron transport chain?

20 pts Electron Transport Chain

True (#5.3 from 9.1)

True or False: Most energy for cellular respiration is generated in this stage

30 pts Electron Transport Chain

36 molecules of ATP are produced in 1 round of cellular respiration

(#10)

By the end of the electron transport chain (and thus, the end of 1 round of cellular respiration), how many molecules of ATP have been generated?

40 pts Electron Transport Chain

Anaerobic

Fermentation is a process similar to cellular respiration, except that it occurs without the presence of oxygen. What word means “without the presence of oxygen”?

10 pts Fermentation

The cytoplasm

Fermentation occurs in the same place in the cell as glycolysis, which is…

20 pts Fermentation

Yeast

Some microorganisms like THIS unicellular eukaryote undergo alcoholic fermentation, which is used to produce alcoholic beverages and also makes bread dough rise

30 pts Fermentation

Lactic acid fermentation – if you’ve ever run so hard your muscles burn, it’s because the lactic acid in your muscles has built up due to lack of oxygen in your body

This other kind of fermentation is a result of strenuous, extended exercise, and named for the type of acid that is produced by the body (not sure? Take a guess!)

40 pts Fermentation

9.3 Fermentation

• Similar to cellular respiration• Anaerobic (without oxygen)• Takes place in the cytoplasm of the cell• 2 types

– Alcoholic fermentation – Ex: yeast – makes bread dough rise, alcoholic beverages

– Lactic acid fermentation – occurs in humans during exercise when your body is short on oxygen; makes muscles “burn”
