| A | B |
|---|
| What is an atom? | Smallest unit of matter |
| How do atoms combine? | Ionically or covalently |
| What is organic material | Any matter that contains carbon |
| What are the 4 organic compounds that make up life? | carbohydrates,lipids,proteins,nucleic acids |
| What is an enzyme? | Certain protein that speeds up chemical reations |
| What is diffusion? | movement of molecules from high to low concentration |
| What is osmosis? | diffusion of water |
| Describe equilibrium | state of balance/even thru space |
| Active transport envolves what? | Energy from cells |
| Passive transport is what? | movement of molecules envolving no energy |
| What do plant cells use for food? | 6 carbon dioxides and 6 waters |
| What waste products do plants have? | glucose and 6 oxygen molecules |
| What material is needed inorder for photosynthesis to occur? | light, enzymes, and chlorophyll |
| What is an easy way to remember cellular repiration? | Opposite of photosynthesis |
| What happens in fermentation? | cellular respiration that converts energy from glucose/not oxygen |
| What material can be found within an element? | protons, neutrons, and electrons |
| What is the charge of an electron? | negative charge |
| What is the charge of a proton? | positive charge |
| What is the charge of a neutron? | neutral charge |
| What substance is used to test for protein? | nitric acid |
| What material is used to test for the presents of carbohydrates? | iodine solution |
| Sodium bicarbonate did what to the process of photosynthesis? | Increased the rate/because it increased the amount of carbon dioxide in the water |
| What does selective permeablility mean? | Cell membrane allows some material thru and not others |
| Carbohydrates are used primarly as a source of what? | Energy by the cells |
| If lipids (fats) are not burned off as energy, they will do what? | Store as fat within your body |
| Chlorophyll is needed for what? | Plants need it for photosynthesis |
| Active transport moves from where to where? | from low to high concentrations |
| Passive transport moves from where to where? | from high to low concentrations |
| How many molecules of glucose are given off during photosynthesis? | one molecule |
| How many molecules of carbon dioxide are need for photosynthesis to take place? | 6 molecules |
| How could you speed up the process of photosynthesis? | Increase the amount of sunlight, increase the amount of water available, or add more carbon dioxide to the plant |
| Producers use light energy to make what organic substance? | Glucose |
| Proteins have what special element in their composition? | Nitrogen |
| How do all consumers obtain energy? | Thru the process of cellular respiration |
| What process causes bread to rise? | Fermenation/yeast breaks down the glucose and carbon dioxide is released |
| What can be found within an atom's nucleus? | protons and neutrons |
