 Show CHAPTER 9 LESSON 1Energy and Life Chemical Energy and ATP KEY QUESTION Why is ATP useful to cells? Cells require energy to perform work, and energy makes life possible. We humans cannot use sunlight as a source of energy, but must take in food made by other organisms, plant or animal, to acquire energy. We are heterotrophs. HeadingMain Idea Chemical Energy and ATPChemical energy is contained in the bonds between atoms. ATP is the molecule that organisms use to temporarily store energy. • Storing Energy • Releasing Energy • How Cells Use ATP Heterotrophs and Autotrophs As you read, circle the answers to each Key Question.

All Rights Reserved.106Chapter 9Photosynthesis Energy comes in many forms, including light, heat, andelectricity. Energy can be stored in chemical compounds, too.For example, when you light a candle, the wax melts, soaks intothe wick, and is burned. As the candle burns, chemical bondsbetween carbon and hydrogen atoms in the wax are broken.New bonds then form between these atoms and oxygen,producing CO2and H2O (carbon dioxide and water). These newbonds are at a lower energy state than the original chemicalbonds in the wax. The energy is released as heat and light inthe glow of the candle’s flame.

The high-energy phosphate bond in this phosphate chain is the key to ATP's energy storage potential.
What are two ways in which cells use the energy provided by ATP?ATP refers to the energy currency of the cell. It is the major molecule for storing and transferring energy in cells. It is used in various biological processes such as secretion, active transport, muscle contraction, synthesis and replication of DNA and movement, respiration, etc.
What is the source of energy for regenerating ATP from ADP in Autotrophs?They regenerate it from ADP as they need it, using energy stored in food. Heterotrophs and Autotrophs The energy to make ATP from ADP comes from food.
What is a 5 carbon sugar molecule that is a part of an ATP?Ribose is a 5-carbon sugar molecule that is part of an ATP molecule. The phosphate groups of ATP are the key to its ability to store and supply energy. ATP releases energy when it breaks bonds between its phosphate groups.
