Cellular Respiration How do organisms get their energy?

Warm Up Activity Take the next few minutes to think about these questions. 1.How do plants get their energy? 2.How do animals get their energy? 3.Are there any similarities/differences between how plants and animals get their energy?

Objectives Define respiration. Discuss how cells obtain energy from glucose. Define ATP. Describe where respiration takes place in the cells.

Cellular Respiration Storing Energy – Who here has gone to the bank with their parents? – At bank have your parents deposited money or withdraw money from the bank? – Cell are similar to banks, in that they can “deposit” carbohydrates and can “withdraw” these carbohydrates when they need energy.

Cellular Respiration Where do plants get their glucose? Where do animals get the majority of their glucose from?

Cellular Respiration in Animals Unlike plants, animals must gain their glucose from another source. In most cases humans will get their glucose from plants and parts of the plants (fruits, grains, etc…) Animals consume carbohydrates, from their food, which are then converted into glucose. Once animals have glucose in their cells, this glucose can be broken down in order to release energy through the process of cellular respiration

Cellular Respiration Respiration: during this process cells break down simple food molecules, such as glucose, and release the energy they contain. This demonstrates which property of living things?

Respiration What comes to mind when you hear the words respiration?

Respiration Respiration sometimes refers to the idea of breathing, or the movement of air in and out of your lungs This leads to the respiration occurring in cells to be referred to as cellular respiration There is a link between these terms as when you breath, your body takes in oxygen. Oxygen is necessary for cellular respiration to occur in most cells

The respiration equation C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O + energy Does any part of this equation seem similar to you? What form of energy is created as a product of respiration? This equation serves as a summary of all the steps that take place in respiration
