Unit 2 & 3.A Review
Unit 2 & 3.a Review
| Question | Answer |
|---|---|
| Photosynthesis | a process that uses sunlight, CO2 and water to make sugars |
| Cellular Respiration | The set of the metabolic reactions and processes that take place in the cells of organisms to convert energy from nutrients into adenosine triphosphate (ATP), and then release waste products. |
| Cells | The basic units of living organisms |
| Anaerobic | A process that does not require oxygen |
| Aerobic | A process that requires oxygen |
| Where does Cellular Respiration takes place? | Mitochondria |
| Describe the mitochondria. | Has a smooth outer membrane; a folded in membrane inner membrane. These folds are called cristae. The space inside the cristae is called the matrix. |
| What is the equation for photosynthesis | 6CO2 + 6H2O -> C6H12O6 + 6O2 |
| What is the name of the main pigment in the chloroplasts, used to absorb light ? | Chlorophyll |
| What are the 2 parts that the photosynthesis process can be split into ? | Light dependent reactions & Light independent reactions |
| Light dependent reactions | Collecting energy from the sun |
| Light independent reactions | Making sugar from the energy provide in the light dependent reactions |
| What are the inputs/reactions in light dependent reactions ? | sunlight and water |
| What is the equation for Cellular Respiration? | C6H12O6 + 6O2 -> 6CO2 + 6H2O |
| What are the inputs/reactions for Cellular Respiration ? | sugar and oxygen |
| What are the outputs/products for Cellular Respiration ? | carbon dioxide and water |
| Stages of Cellular Respiration | 1. Glycolysis - Pre- Krebs 2. Krebs Cycle 3. Electron Transport |
| The 2 types of Fermentation. | Alcoholic Fermentation and Lactic Acid Fermentation |
| What does lactic acid cause? | Muscle Soreness |
| Anabolic Reactions | small molecules are combined into large molecules for repair, growth, or storage. |
| Catabolic Reactions | Breaks down molecules to release their stored energy |
| Chromosomes | are made made of DNA |
| Prokaryotic Chromosomes | DNA molecules are found on the cytoplasm |
| Eukaryotic Chromosomes | Have multiple chromosomes |
| How many chromosomes do an human have ? | A human have 46 Chromosomes |
| What is the cell cycle ? | a series of events durning which the cells grows, prepares for division, and then divides to form two daughter cells. |
| What are the four stages in which a Eukaryotic Cell Cycle consists of ? | G1 , S , G2 , and M |
| What is the longest stage in the cell cycle ? | Interphase |
| What happened in the interphase stage of the cell cycle ? | it grows, replicates its chromosomes, and prepares for cell division |
| What 2 stages is the M stage split into? | the M stage is split into mitosis and cytokinesis |
| Sexual Reproduction | offspring inherits traits from both parents , requires two parents |
| Asexual Reproduction | offspring inherits traits from the parent, requires on parent |
| What does both sexual and asexual reproduction have in common ? | produces offspring |
| What happens in the M stage ? | nuclear division (mitosis) followed by cytoplasmic division (cytokinesis) |
| Mitosis | a type of cell division that results in two daughter cells |
