Question | Answer |
What carries the chemical energy for most cell processes? | ATP |
What do carbon based molecules in food store? | Chemical energy |
What are the most important energy sources in food? | Carbohydrates and lipids |
Does energy come directly from food? | No |
What is ATP? | A molecule that transfers energy from the breakdown of food molecules to cell processes. |
What do cells use ATP for? | Building molecules and moving materials by active transport |
When is energy released by ATP? | When a phosphate group is removed from the molecule |
How many phosphate groups does ATP have? | Three |
What is ADP? | A lower energy molecule that can be converted into ATP by the addition of a phosphate group |
What are calories? | Measures of energy |
How many molecules of ATP does the breakdown of glucose yield? | 36 |
Which molecule stores the most energy? | Lipids |
Do all organisms need sunlight and photosynthesis as a source of energy? | No |
What is chemosynthesis? | A process by which some organisms use chemical energy instead of light energy to make energy storing carbon based molecules. |
What is a producer? | Organisms that produce the source of chemical energy for themselves and other animals |
What is photosynthesis? | A process that captures energy from sunlight to make sugars that store chemical energy. |
What kind of light do plants absorb for photosynthesis? | Visible light |
What is chlorophyll? | A molecule in chloroplast that absorb some of the energy in visible light and makes the plants green |
Where does photosynthesis in plants occur? | In the chloroplast |
What are the two main parts of chloroplasts needed for photosynthesis? | The grana and the stroma |
What are grana? | Stacks of coin shaped, membrane enclosed compartments called thylakoids |
What is found inside of thylakoids? | Chlorophyll, proteins, and other light absorbing molecules |
What is stroma? | The fluid that surrounds the grana inside a chloroplast |
What is the equation for photosynthesis? | 6CO2+6H2O => C6H12O6+6O2 |
Why do plants need simple sugars? | To build starch and cellulose molecules |
During the light dependent reactions, what is energy captured and transferred in the thylakoids membrane by? | Photosystems |
What are the main functions of the light dependent reactions? | To capture and transfer energy |
What is the energy from elections used for? | To make molecules that act as energy carriers or ATP and NADPH |
Which molecules go on from the light dependent reactions to the later stages of photosynthesis? | ATP and NADPH |
What is cellular respiration? | A process releases chemical energy from sugars and other carbon based molecules to make ATP when oxygen is present |
What is an aerobic process? | Oxygen needs to take place |
Is cellular respiration an aerobic process? | Yes |
What is glycolysis? | A process that splits two three-carbon molecules s makes two molecules of ATP. |
Is glycolysis an anaerobic process? | Yes |
What is an anaerobic process? | A process that doesn't require oxygen |
What two parts in mitochondria are involved in cellular respiration? | The matrix and the inner mitochondrial membrane |
What are the two cycles in cellular respiration? | Krebs Cycle and Electron Transport |
What is the Krebs Cycle? | A cycle that produces molecules that carry energy to the second part of cellular respiration |
How many ATP molecules do Glycolysis make? | 2 |
How many ATP molecules do cellular respiration make? | 34-36 |
Where does glycolysis take place? | The cytoplasm |
What are the products of glycolysis? | Pyruvate and the electron carrier NADH |
What happens when oxygen is not there to pick up electrons? | The production of ATP without oxygen continues through the anaerobic processes of glycolysis and fermentation |
What is fermentation? | It doesn't make ATP but allows glycolysis to continue. It removes electrons from NADH molecules and recycles NAD+ molecules for glycolysis. |
What would happen if NAD+ didn't pick up high energy electrons from the splitting of glucose? | Glycolysis would stop |
What is lactic acid? | C3H6O3 is what causes your muscles to burn during hard exercises |
What is the role of fermentation? | To provide glycolysis with a steady supply of NAD+ |
