27
Q

What is photosynthesis?

A

The process through which autotrophs convert sunlight energy into chemical energy (glucose).

28
Q

How does photosynthesis happen?

A

Through a series of chemical reactions.

29
Q

What does photosynthesis store?

A

Energy in the form of organic compounds (glucose).

30
Q

What’s the photosynthesis equation in words?

A

Sunlight+Water+Carbon Dioxide–>Glucose+Oxygen

31
Q

What’s the photosynthesis equation formula?

A

Sunlight+6H2O+6CO2–>C6H12O6+6O2

32
Q

What’s the first stage of photosynthesis called?

A

Light reactions.

33
Q

What happens in the first stage of photosynthesis?

A

Light energy is absorbed and turned into chemical energy (ATP).

34
Q

Where is the light energy absorbed?

A

Pigments in the chloroplasts.

35
Q

Where does Light Reactions happen?

A

The chloroplasts.

36
Q

What is a pigment?

A

A compound that absorbs light.

37
Q

What’s an example of a pigment?

A

Chlorophyll.

38
Q

Why do plants often appear green?

A

Chlorophyll is absorbing most of the other colors and is reflecting green.

39
Q

What’s the second stage of photosynthesis called?

A

Dark Reactions (Calvin Cycle).

40
Q

What happens in the second stage of photosynthesis?

A

Chemical energy (ATP) is used to make organic compounds (glucose).

41
Q

What is the purpose of cellular respiration?

A

To make ATP for your cells.

42
Q

What are the reactants of cellular respiration?

A

Glucose and oxygen.

43
Q

What are the products of cellular respiration?

A

ATP, carbon dioxide, and water.

44
Q

What type of organisms go through cellular respiration?

A

All organisms.

45
Q

What form of energy do all cells need?

A

ATP.

46
Q

Why is breathing is essential for cellular respiration?

A

Because you need to take oxygen in and breathe carbon dioxide out.

47
Q

Why is fermentation not efficient?

A

Because not as much energy is created compared to cellular respiration.

48
Q

How is fermentation similar to cellular respiration?

A

It’s basically the same as glycolysis because it doesn’t need oxygen, takes place in the cytoplasm, and doesn’t produce much ATP.

49
Q

How is fermentation different from cellular respiration?

A

It doesn’t need oxygen, takes place only in the cytoplasm, and doesn’t make much ATP, which is the opposite from stage two of cellular respiration. It also uses bacteria and yeast, and creates ethanol and lactic acid.

50
Q

What’s the purpose of photosynthesis?

A

To create chemical energy in the form of glucose.

51
Q

What are the reactants of photosynthesis?

A

Sunlight, carbon dioxide, and water.

52
Q

What are the products of photosynthesis?

A

Glucose and oxygen.

53
Q

What role do pigments play in photosynthesis?

A

They absorb the sunlight.

54
Q

What types of organisms go through photosynthesis?

A

Autotrophs/producers.

55
Q

Why is photosynthesis important for all living things and not just plants?

A

Because it creates glucose, which all things need to convert into ATP in order to survive.

56
Q

Carbon dioxide is a product of what?

A

Cellular respiration.

57
Q

What happens in the cytoplasm and mitochondria?

A

Cellular respiration.

58
Q

Where is oxygen given off?

A

Photosynthesis.

59
Q

What makes glucose?

A

Photosynthesis.

60
Q

What uses light energy?

A

Photosynthesis.

61
Q

What uses chlorophyll?

A

Photosynthesis.

62
Q

What includes glycolysis?

A

Cellular respiration.

63
Q

What captures energy in chloroplasts?

A

Photosynthesis.

64
Q

What turns food into ATP?

A

Cellular respiration.

65
Q

What is required for all life on Earth?

A

Cellular respiration.
