| Question | Answer |
|---|---|
| Energy | All living things need energy, which is defined as the ability to do work. |
| Food | Consist of organic molecules that store energy in their chemical bonds. |
| Autotrophs | are organisms that make their own food. |
| Photosynthesis | Most autotrophs use the energy in sunlight to make food in a process called Photosynthesis. |
| Producers | Autotrophs are also called Producers. They Produce food not only for themselves but for all other living things as well (which are know as consumers. |
| Heterotrophs | Are living things that cannot make their own food. |
| Consumers | Instead, they get their food by consuming other organisms, which is why their called Consumers. |
| Glucose | is a simple carbohydrate with the chemical formula C6, H12, O6 . it stores chemical energy in a concentrated , stable form. |
| Cellular respiration | The process in which glucose is broken down and ATP is made is called Cellular respiration. |
| Light reaction | This stage uses Water and changes light energy from the sun into chemical energy stored in ATP and NADPH ( another energy carrying molecule) |
| Calvin cycle | This stage combines carbon from carbon dioxide in the air and uses the chemical energy in ATP and NADPH to make glucose. |
| Grana | Each chloroplasts contains neat sacks called grana. |
| Thylakoid membranes | The grana consist of sac-like membranes, known as Thykaloid membranes. |
| Photosystems | Which are groups of molecules that include chlorophyll. |
| Chlorophyll | A green pigment. The light reactions of photosynthesis occur in the Thylakoid membranes. |
| Stroma | The Stroma is the space outside the Thykaloid membranes. This is where the reactions of the Calvin cycle take place. |
| Electron transport chain | They are carried by a series of electron-transport, which make up an electron transport chain. |
| Chemosynthesis | Some bacteria make food by another process, which uses chemical energy instead of light energy. This process is called chemosynthesis. |
| Glycolysis | It takes place in the cytosol of the cytoplasm. |
| Anaerobic respiration | Cellular respiration that proceeds without oxygen is called Anaerobic respiration. |
| Aerobic respiration | Cellular respiration that proceeds in the presence of oxygen is called aerobic respiration. |
| Krebs Cycle | These molecules enter the matrix of a mitochondrion, where they start the Krebs Cycle. |
| Fermentation | An important way of making ATP without oxygen is called fermentation. |
| Lactic acid fermentation | Pyruvic acid from glycolysis changes to lactic acid. |
| Alcoholic Fermentation | pyruvic acid changes to alcohol and carbon dioxide. |
