Q

Equation for photosynthesis

A

light (from he sun) + 6CO2 + 6H2O ——> C6H12O6 + oxygen6O2 + Heat
Light+carbon Dioxide +water —-> glucose+oxygen+ heat

24
Q

where does photosynthesis specifically occur?

A

it occurs in the chloroplast (a specific organelle) of plants and photosynthetic bacteria

25
Q

3 factors that can impact the rate of photosynthesis

A

Availability of water
Temperature (Goldilocks zone not hot or cold)
Amount of light- plants do not grow in dark

26
Q

what happens to the total amount of energy as photosynthesis takes place

A

stay the same

due to the law of conservation of matter

27
Q

what happens to the amount of USABLE ENERGY as photosynthesis takes place

A

Decreases

due to energy is transferred, a lot is lost to heat

28
Q

Radient energy

A

aka Sunlight,is needed for photosynthesis to occur

29
Q

The ultimate source of energy for all life on this planet is the ___

A

SUN

30
Q

who wanted to prove that plants use materials from the soil to perform photosynthesis by planting a willow tree

A

Van Helmont

31
Q

ATP

A

(Adenosine Triphosphate) is the energy molecule living things use to do work

32
Q

ATP requires ____

A

ENERGY

33
Q

Cellular Respiration

A

the process by which the energy stored in the bonds of glucose is used to recharge ADP to make ATP

34
Q

Equation for Cellular respiration

A

C6H1206+602—> 6C02+6H2O+ ENERGY

35
Q

Where in a cell does cellular respiration take place

A

Mitochondria

36
Q

Mitochondria

A

All Eukaryotes( have a nucleus) ; Animals,plants

37
Q

2 factors that impact cellular respiration

A
  • how much glucose (energy) there is available

- Amount of oxygen

38
Q

Aerobic Respiration

Result:

A
  • Happens in the presence of oxygen
  • Normally happens
  • Result: 36 ATP per glucose
  • A slow and methodical process
39
Q

Anaerobic Respiration

A
  • Happens w/o the process of oxygen
  • Happen when you need a quick burst of energy or if you exercise long period of time
  • Result: 2 ATP per glucose + lactic acid
  • Fast and intense process
40
Q

Energy is stored in the ______ of molecules

A

Bonds

41
Q

Cellular respiration “__________” ADP molecules by adding a phosphate to them to make ATP which can then be used to do work

A

Recharges
