17
Q

light reactions

A

light energy is converted to chemical energy

18
Q

cellular respiration

A

breaking chemical bonds of organic food molecules and releasing energy that can be used by the cells.

19
Q

what is energy released and trapped in

A

molecules of ATP until needed

20
Q

what part of ATPs structure makes it an ideal source of energy for the cells because

A

ATP can easily release and store energy by breaking down an re- forming the bonds between its phosphate groups

21
Q

what is the ultimate source of energy for all plants

A

the sun

22
Q

aerobic

A

respiration with air

23
Q

anaerobic

A

respiration without air

24
Q

what substance goes through glucose and how

A

light energy goes into glucose and ATP helped in get there

25
Q

in ATP useable or not

A

yes

26
Q

is glucose useable or not

A

not useable

27
Q

where is not used glucose put

A

in the starch molecules

28
Q

starch is a long chain of what

A

carbohydrates

29
Q

fermentation

A

aerobic respiration-net gain of ATP =2 ( from glycolysis)

30
Q

if CO2 is present what happens

A

aerobic respiration takes place in mitochondria yielding 36 ATP
