Q

Describe how photosynthesis and respiration are processes that depend on one another.

A

Photosynthesis gets light energy and converts it into sugars and respiration breaks down the sugar to make energy

Q

Why is the calvin cycle known as the “carbon-fixation” cycle?

A

carbon from CO2 is “fixed” into C6H12O6 (glucose)

Q

Why does cholorphyll a and b look green to the human eye?

A

It absorbs red and blue best but reflects green.

17
Q

Why do carotenoids look orange and red to the human eye?

A

It reflects orange and red,

Q

Where does the kreb cycle take place?

A

matrix of mitochondria

23
Q

Where does ETC take place?

A

inner membrane of mitochondria

24
