ATP and Cellular Respiration

Question 1

2 ways for muscles to get ATP

Answer 1

1. Glycolysis
2. Aerobic Respiration

Question 2

Glycolysis

Answer 2

-“glucose breaking”
-happens in cytoplasm
-requires no oxygen

Question 3

Glycolysis process

Answer 3

-use 2 ATP’s
-glucose or C6H12O6 is broken down into two 3-Carbon pyruvic acid molecules
-produces lactic acid and 4 ATPs

Question 4

Pros and cons of Glycolysis

Answer 4

Pros:
-fast
-muscles get ATP quick
Cons:
-lactic acid causes muscle cramps
-energy doesn’t last

Question 5

Aerobic Respiration

Answer 5

-with oxygen
-takes place in mitochondria
-muscle cells have a lot of mitochondria
-2 phases: Krebs cycle and electron transport chain

Question 6

Krebs cycle and Electron transport chain

Answer 6

-pyruvic acid (PA) and fatty acid (FA) enters mitochondria
-Using O2 and electron acceptors FAD and NAD-> PA and FA are broken down and release CO2
-In electron transport chain FADH2 and NADH convert into ATPs and water
-creates 32 ATPs
