chemical energy and ATP

Question 1

what does ATP serve as ?

Answer 1

it serves as an energy carrier in cells

Question 2

what kind energy do molecules store in foods in their bonds

Answer 2

chemical energy

Question 3

what are ATP’s components

Answer 3

• 3 phosphate groups
• 1 ribose (sugar)
• 1 adenine

Question 4

what happens when energy is needed ?

Answer 4

one terminal phosphate group is removed

Question 5

what happens when one phosphate group is removed?

Answer 5

energy is removed, so that it can be used by the cell to carry out its function. also ATP is reduced into ADP

Question 6

what carbon-based molecule is most-likely to broken down for ATP

Answer 6

carbohydrates

Question 7

what carbon-based molecule stores the most energy

Answer 7

Fats

Question 8

what carbon-based molecule is least likely to be broken down and why ?

Answer 8

proteins are the least-likely to be broken down. Because it contains amino acids which are not needed for energy.

Question 9

how much energy do Carbohydrates -Lipids -Protein each contain?

Answer 9

carbohydrates: 4 calories per mg
lipids(fats): 9 calories per mg
proteins: 4 calories per mg

Question 10

what is the the difference between photosynthesis and chemosynthesis?

Answer 10

photosynthesis can only happen in the presence of light energy
chemosynthesis can happen without the presence of light energy

Question 11

how is chemosynthesis similar to photosynthesis?

Answer 11

Photosynthesis and chemosynthesis are both processes by which organisms produce food
