 * Where do organisms get energy?**
 * Heterotrophs get it from the food they eat, while Autotrophs get energy from the sun.**

1) calorie– the amount of energy needed to raise the temperature of 1 gram of water, 1 degree Celsius. Calorie - With a CAPITAL C, on food packages means kilocalorie = 1000 calories

2) What is cellular respiration? – The process of releasing energy from food.

3) Cellular Respiration – The process of releasing energy from food by breaking bonds.

4) General equation for Cellular Respiration –

C6H12O6 + 6(O2) --- 6(CO2) + 6(H2O)+ energy

5) Aerobic – In the presence of Oxygen gas.

6) Anaerobic – In the absence of Oxygen gas.

7) What is the relationship between photosynthesis and cellular respiration? – They are the reverse of each other.

8) Homeostasis – Stable internal conditions, state of well being for the cell.

9) ATP - Energy used by the cell.

10) Mitochondria - Organelle, Powerhouse of the cell

1A) Why do all organisms need food? - To provide energy to its cells

1B) Why do macromolecules differ in the amount of energy they contain? Differences in chemical structure.

2A)Write the overall reaction for cellular respiration. -

2B) How does the process of cellular respiration maintain homeostasis at the cellular level? - It replaces the energy needed to keep the cell running smoothly

<span style="font-family: 'Arial Black',sans-serif; font-size: 12pt;">3B)How is the chemical energy in glucose similar to money in a savings account? <span style="font-family: 'Arial Black',sans-serif; font-size: 12pt;">4)The Greek word glukus means “Sweet” and the Latin word lysis refers to “a process of loosening or decomposing”. Based on this information write a definition for the word glycolysis.

Aerobic Respiration Total = 36 ATP Anaerobic Respiration Total = 2 ATP
