Cellular Respiration

Question 1

the process of breaking down food to produce ATP ( energy currency ) in the presence of oxygen.

Answer 1

Cellular respiration

Question 2

Three stages, GOAL: ATP!

Answer 2

O1. Glycolysis
O2. Krebs Cycle/ Citric Acid Cycle
O3. Electron Transport Chain

Question 3

Glyco

Answer 3

GLYCOLYSIS:

Question 4

Lysis =

Answer 4

breakdown

Question 5

Occurs in the cytoplasm of the cell where molecules of Glucose are broken down into 2 molecules of Pyruvic Acid.
Cells must use (invest) 2 ATP.

Answer 5

GLYCOLYSIS

Question 6

involves aerobic process
occurs in the matrix of the mitochondria
Pyruvic Acid from Glycolysis enters to form 2 ATP & 6 NADH & 2 FADH & CO2

Answer 6

KREBS CYCLE / CITRIC ACID CYCLE:

Question 7

The mitochondria are the organelle where the final stages of cellular respiration occur.

Answer 7

Site of Cellular Respiration

Question 8

-Occurs in the folds of the Inner Membrane of the Mitochondria ( Cristae )
- Involves aerobic process
- NADH and FADH2 enter this stage.
- Produces 32 ATP and H2O

Answer 8

ELECTRON TRANSPORT CHAIN:

Question 9

Process by which energy is released from glucose when oxygen is NOT available.
- only release 2 ATP per molecule of glucose.

Answer 9

FERMENTATION:

Question 10

-is a biological process that converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products.

Answer 10

ALCOHOL

Question 11

-is a metabolical process by which glucose and other six-carbon sugars are converted into cellular energy and the metabolite lactate.

Answer 11

LACTIC ACID
