Photosynthesis

Photosynthesis

Energy & Life

Slide 2

Overview of Photosynthesis

Overview of Photosynthesis

Slide 3

Autotrophs

Autotrophs

Plants and some other types of organisms that contain chlorophyll are able to use light energy from the sun to produce food.

Slide 4

Autotrophs

Autotrophs

Autotrophs include organisms that make their own food

Autotrophs can use the suns energy directly

Euglena

Slide 5

Heterotrophs

Heterotrophs

Heterotrophs are organisms that can NOT make their own food

Heterotrophs can NOT directly use the suns energy

Slide 6

Energy

Energy

Energy Takes Many Forms such as light, heat, electrical, chemical, mechanical

Energy can be changed from one form to another

Energy can be stored in chemical bonds & then released later

Candles release energy as HEAT & LIGHT

Slide 7

ATP  Cellular Energy

ATP Cellular Energy

Adenosine Triphosphate

Contains two, high-energy phosphate bonds

Also contains the nitrogen base adenine & a ribose sugar

Slide 8

ADP

ADP

Adenosine Diphosphate

ATP releases energy, a free phosphate, & ADP when cells take energy from ATP

One phosphate bond has been removed

Slide 9

Sugar in ADP & ATP

Sugar in ADP & ATP

Called ribose

Pentose sugar

Also found on RNA

Slide 10

Importance of ATP

Importance of ATP

Principal Compound Used To Store Energy In Living Organisms

Slide 11

Releasing Energy From ATP

Releasing Energy From ATP

ATP is constantly being used and remade by cells

ATP provides all of the energy for cell activities

The high energy phosphate bonds can be BROKEN to release energy

The process of releasing ATPs energy & reforming the molecule is called phosphorylation

Slide 12

Releasing Energy From ATP

Releasing Energy From ATP

Adding A Phosphate Group To ADP stores Energy in ATP

Removing A Phosphate Group From ATP Releases Energy & forms ADP

Loose

Gain
