Energy From Macromolecules: Carbohydrates, proteins, and lipids can all serve as energy sources for cells. Carbohydrates and proteins yield only 4 calories of usable
energy per gram. Lipids are more complex than carbohydrates and provide more energy, 9 calories per gram. Carbohydrates are a cell’s best source for quick energy.
Proteins are broken down much more slowly than carbohydrates. Organisms often convert carbohydrates and proteins that are not needed for energy into lipids. Cells store
energy into lipids.

**Fill in the boxes in the picture
above with: ATP, ADP
Word Bank: ATP, Energy, ADP
Above are the steps of _________________ ______________________. Which process makes more ATP molecules and thus provides more energy?
Cellular respiration or fermentation
Chemical energy is stored in the bonds that hold carbohydrates and other organic compounds together.
Cells release this energy through respiration. Organisms then use this energy to carry out a variety of
activities. When energy is needed in the cell, chemical energy is converted from storage molecules, such
as sugar, into adenosine triphosphate, or ATP. ATP then delivers the energy to the places in the cell that
need it. ATP is a nucleic acid with 3 phosphate groups in a chain. The phosphate tail of the ATP
molecule holds the usable energy. To release the stored energy, the bonds between the phosphates in
ATP must be broken. When a phosphate is removed, a molecule with 2 phosphates is left called
adenosine diphosphate, or ADP. ADP can be recombined with a free phosphate to form a new molecule
of ATP. Combining ADP with free phosphates is called phosphorylation. ATP is like a rechargeable
battery. A rechargeable battery may start out filled with chemical energy. As the battery is used, it gives
up the energy. The depleted battery is then recharged so it can be used again. ATP is like the recharged
battery and ADP is the lower-energy form like the used up battery.

A cladogram is a tree-like diagram that shows evolutionary relationships. Each branch
shows where a new group of organisms, called a clade, emerged from an existing group.
The cladograms below shows the emergence of the 6 kingdoms. Eubacteria are classified
in their own kingdom due to differences in their RNA and the presence of peptidoglycan in
their cell walls. Scientists think Protista was the first kingdom of eukaryotic organisms.

evolutionary time line.
