Test 2: Photosynthesis, Respiration, Human body, Homeostasis, Immune Response
| Term | Definition |
|---|---|
| Allergy | When a persons immune system over reactes to substances that are normally harmless |
| Antibody | Produced by your body an antibody is a protien used by the immune system to identify invaders |
| Antigen | Produced by the pathogen a protein on the surface of the pathogen that antibodys attach to to identify pathogens as invaders |
| ATP | A energy storing molecule made during cell respiration. Adenosine TriPhosphate |
| Cellular Process | A chemical process that occurs in cells. Examples include Photosynthsis and Respiration, Enzymes and Cell transport. |
| Chloroplast | Organelle that is the site of photosynthesis. Looks like a bean full of pancakes |
| Disease | A conditions that prevents the body from working as it should |
| Dynamic Equlibrium | another word for homeostasis. To maintain internal stability while external conditions change |
| Feedback Mechnisim | A cycle to maintain homeostasis. Follows the following pattern. 1. Stimulus, 2. Signal. 3. Response. Sometimes you return to normal, Negitive feedback. Sometimes you produce more stimulus, Positive feedback |
| Gas Exchange | The process of taking in and releasing oxygen and carbon dioxide |
| Glucose | Sugar that is the major source of energy for living things. C6H12O6 |
| Guard cells | Cells on the underside of leaves that open and close to allow for gas exchange |
| Homeostasis | Maintaining a stable internal envrionment while external environmnetal conditions change. |
| Immune System | The bodies defence against disease causing pathogens |
| Insulin | A hormone that signals cells to uptake glucose, resulting in a lower blood sugar |
| Microbe | Any microscopioc organism |
| Mitochondria | Organelle that is the site of cell respiration. produces ATP. Looks like a bean full of bacon |
| Pancreas | An organ that makes insulin |
| Pathogen | an organism that invades the body causing sickness and disease. Bacteria, virus, fungi or parasite. Germ, and microbe are both also pathogens |
| Photosynthesis | Cell process that happens in the cholorplast that uses sunlight to turn water and carbon dioxide into glucose and oxygen |
| Respiration | Cell process that happens in the mitochondria that uses energy stored in glucose and oxygen to produce carbon dioxide water and ATP |
| Stimulus | A change that causes a reaction |
| Vaccine | a substance made of a dead or weakend form of a virus that teaches your immune system how to make antibodies so you can fight of pathogens faster. (ONLY WORKS FOR VIRUSES) |
| Virus | A non-living particle that invades cells to reproduce and causes sickness and disease |
| Body System | An system consisting of a group of organs that work together to perform one or more functions. |
| Oxygen | A gas molecule produced during photosynthesis and used in cell respiration to make ATP |
| Carbon dioxide | A gas molecule produced during cell respiration and used in photosynthesis to make glucose |
| Circulatory system | Circulates materials around your body. This includes providing cells with nutrients like oxygen and glucose and transporting waste products and toxins like CO2 |
| Respiratory system | Exchanges gases with the environment. Obtains oxygen from the air necessary for cell respiration and releases CO2 back into the atmosphere |
| Musculoskeletal system | Sometimes referred to sepearly as Muscle system and Skeletal systems they function together to provide the body with central structure the ability to move and serves to protectively house major organs |
| Integumentary system | Made up of mostly your skin separates the inside of your body from the outside. Provides protection from invaders like bacteria and parasites |
| Endocrine system | Works as a communication center organizing sending chemical signals known as hormones to coordinate body processes |
| Nervous system | Body control center Analyzes sensory information and sends signals to appropriate muscles in response. |
| Excratory system | Removes toxic compounds from the body by filtering blood and excreting out the waste as urine |
| Digestive system | Breaks down food into its component parts so nutrients can be absorbed into cells |
| Equation for photosynthesis | CO2 + H2O --> C6H12O6 + O2 |
| Equation for Respiration | C6H12O6 + O2 --> CO2 + H2O |
| What types of living things carry out photosynthesis | Plants |
| What types of living things carry out respiration | All living things |
| Positive Feedback | Feedback that produces more stimulus and pushes you further outside normal |
| Negitive Feedback | Feedback that counteracts the stimulus and returns you to normal |
| Thermoreguation | Your bodies ability to maintain a stable internal temperature |
| Osmoregulation | Your bodies ability to maintain the proper water balance |
| CO2 and O2 regulation | Your bodies ability to maintain the proper concentration of carbon dioxide and oxygen |
| Blood glucose regualtion | Your bodies ability to maintain stable blood glucose concentrations |
| Diabetes type 1 | A disease were the pancreas does not make insulin caused by genetic disorder |
| Glucagon | A hormone that causes the liver to release glucose resulting in an increse in blood sugar |
| White blood cell | A cell made by the immune system that produces antibodies (b-cells) or attacks invaders (T-cell) |
| Diabetes type 2 | A disease where the body does not respond to insuin due to excessive glucose consumption |
| AIDS | The disease that caused by HIV that attacks the immune system |
