Glucose

28
Q

what is reduced in photosynthesis

A

O2

29
Q

What is the role of ATP synthase

A

To create ATP

30
Q

Why and how is the H+ concentration gradient produced?

A

Know

32
Q

What step does fermentation and cellular respiration have in common?

A

Glycolisis

33
Q

What is the by product of Fermentation

A

Recycling of electron carriers

34
Q

Where does glycolisis occur in the cell

A

Cytoplasm

35
Q

Where do the Light dependant reactions occur

A

Thykaloid membrane

36

Origins of Cholorplast

A

likely evolved from engulfed prokaryotes that once lived as independent organisms

39
Q

Source of energy for ecosystems

A

Sunlight

40

Inhibitor which ataches directly onto the acitve site blocking the substrate from going onto the active site

41
Q

Noncompetitive Inhibitor

A

Inhibitor that attaches anywhere but the active site and

42
Q

Why does fermentation occur

A

it occurs becuase of a lack of oxygen its why your musles get sore if not enough oxygen gets to them

Where does the Calvin cycle occur

A

Stoma

44
Q

Where does the Kerb and ETC occur

A

In the Midochondria
