flowering plants

Question 13

Cellular respiration

Answer 13

done by both plants and animals; havesting energy from food

Question 14

Photosynthesis

Answer 14

harvesting energy from the sun’s energy

Question 15

ATP

Answer 15

bonds are store in the 3 phosphates

Question 16

Energy is absorbed each time phosphate is broken from the molecule. True or False?

Answer 16

False, energy is released

Question 17

what requires ATP?

Answer 17

muscle contractons; transporting molecules; some enzyme reactions

Question 18

Steps in Cellular respiration

Answer 18

Glycolysis, The Krebs Cycle, Electron Transport Chain,

Question 19

Glycolysis

Answer 19

glucose splits into 2 pyruvic acid molecules

Question 20

The Krebs Cycle

Answer 20

pyruvic acid broken down into CO2

Question 21

Electron Transport Chain

Answer 21

electron carriers release their electrons to provide energy, this creates a H+ pump, creating more energy which creates lots of ATP molecules

What is the final electron acceptor in the Electron Transport chain?

Answer 30

O2

Question 31

What waste is created in the electron transport chain?

Answer 31

H20

Question 32
