Previous knowledge on chloroplast adaptations

Adaptation means

• ability to a wide variety of features in an environment

• what feature is present that enables a particular function to be carried out

• same thing as evolution

• having several functions

The thylakoid lumen has a space for ................... and as such is able to establish a ........................

• photolysis, electrochemical gradient

• cyclic photophosphorylation, ATP gradient

• calvin cycle, sugar gradient

• soaking up protons, proton gradient

One adaptation of the granum is that it has ....................... which enables it to ............................

• Photosystems, trap and convert light energy into ATP and NADPH

• Photosynthetic pigments, to help in photolysis

• electron carriers, to transfer protons

• enzymes, to catalyse production of glucose

The increased surface area of a granum is due to

• Having a cylindrical structure

• being connected to the lamellae

• Having many disc-shaped thylakoids

• having may photosystems

Which type of ribosome is found in the chloroplast?

• 80S

• 70S

• 60S

• 50S

Which enzyme is responsible for ATP synthesis and where can it be found in the chloroplast?

• Atp synthetase, thylakoid membrane

• ATPase, lumen

• Glycogen synthase, stroma

• ATP synthase, thylakoid membrane

The chloroplast as a whole is adapted for photosynthesis and ATP as it has ...................... and ......................

• ATP synthase and photosystems

• Photosynthetic pigments and photosystems

• ATP synthase and ATPase

• High level photophosphorylation

What adaptation does the stroma have that enables it to carry out photosynthesis?

• Enzymes required to produce ATP

• consists of a colourless fluid that baths the grana

• contains more photosystems to maximum light absorption

• contains enzymes that are involved in sugar production
