Storing Energy

When a cell has energy available, it can store small
amounts of it by adding phosphate groups to ADP
molecules, producing ATP.

8

Multiple Choice

Which of these is a way that cells can STORE energy?

(Read carefully!)

1

Making ATP

by adding a phosphate to ADP

2

Making ADP

by removing a phosphate from ATP

Releasing Energy

When a cell needs energy, it can release it by breaking
the bond between the second and third phosphate
groups in ATP.

ATP Production

Cells must produce ATP. In photosynthesis, plants convert
the energy of sunlight into chemical energy stored in the
bonds of sugar. Sugar is a better way to store larger amounts of energy in a cell for a longer amount of time. The energy from sugar is used to add phosphates to ADP to "recharge the battery".

ADP

3

sugar

4

water

15

Multiple Choice

How is the energy from sugar used in cells?

1

to make ATP

2

to make ADP

3

to transport ions through the cell membrane

4

to move around

Heterotrophs and Autotrophs

Organisms that make their own food are autotrophs.
Plants and phytoplankton are autotrophs.
Organisms that obtain food by consuming other living things
are heterotrophs.
