Chapter 6 Vocabulary
| Question | Answer |
|---|---|
| What is photosynthesis? | It is the process in which autotrophs make their own food using the energy in light and CO2 and H20. |
| What is the photosynthesis equation? | 6 CO2+6 H2O--sunlight--> C6H12O6+6 O2 (Carbon dioxide+water--light--> carbohydrate+oxygen) |
| What was Van Helmont's experiment? | Van Helmont's experiment studied what plants used to increase its mass. Though his experiments of a plant as a seedling to a larger size, he concluded that water was a major part of the plant's growing mass. |
| What was Joseph Priestly's experiment? | Joseph Priestly's experiment consisted of placing a candle under a jar until it went out. He then placed a sprig of mint under the jar with the candle and the candle was able to burn longer. He concluded that the plant used and made gases. |
| What is an autotroph? | It is an organism that is able to use a source of energy to produce its food from inorganic raw materials. (Ex. Plants) |
| What is a heterotroph? | It is an organism that cannot produce its own food but obtains energy from the food it eats. (Ex. Animals) |
| What are pigments? | They are colored substances that absorbs or reflects certain wavelengths of light. |
| What is chlorophyll II? | It is the most dominant color of chlorophyll in plant cells. Chlorophyll is the principal pigment of green plants and chlorophyll II is the one that we see with the naked eye. |
| What is AMP? ADP? ATP? | AMP is adenosine monophosphate. It is made up of an adenosine molecule and a phosphate molecule. ADP is adenosine diphosphate. It has an added phosphate. ATP is adenosine triphosphate. It has another added phosphate. |
| What is NADP+? NADPH? | NADP+ is an electron carrier inside of plant cells. It can store extra electrons in its energy levels. NADPH is NADP+ that has accepted a pair of high-energy electrons. The conversion is one way in which some of the energy of light can be chemically tra |
| What are the light reactions? | They are the reactions of photosynthesis that require light. |
| What are the dark reactions? | They are the reactions of photosynthesis that do not require light but use energy produced and stored during light reactions to make glucose. |
| What are things inside the chloroplast that are saclike and contain chlorophyll? | They are photosynthetic membranes. |
| What is a cluster of pigment molecules within a photosynthetic membrane called? | Photosystems |
| What is the process in which high-energy electrons are transferred along a series of electron-carrier molecules in a membrane? | Electron transport |
| What is the name given to the cycle of dark reactions in photosynthesis called? | Calvin cycle |
| What is the production of ATP by the conversion of glucose to pyruvic acid called? | Glycolysis |
| What is the process that involves oxygen and breaks down food molecules to release energy called? | Respiration |
| What is a process that requires oxygen classified as? | Aerobic |
| What is the continuing series of nine reactions in cellular respiration that produces carbon dioxide, NADH, and FADH2 called? | Krebs cycle |
| What is fermentation? | It is the process that enables cells to carry out energy production in the absence of oxygen; breakdown of glucose and release of energy in which organic substances are the final electron acceptors. |
| What is a process that does not require oxygen classified as? | Anaerobic |
| What is the anaerobic process of glucose breakdown that produces lactic acid? | Lactic acid fermentation |
| What is fermentation that produces alcohol called? | Alcoholic fermentation |
