Apr 24, 2017 · Advertisement. In cellular respiration, glucose is broken down by the removal of its hydrogen atoms. That process releases energy in the form of electrons, negatively charged particles that fuel all of a cell's other work in later reactions. So, plants make the glucose and everything down the line—from plant-eaters to the carnivores that eat ...

are organisms that capture from nonliving sources and transfer that energy into the living part of the ecosystem. They are also able to make their own food. Most autotrophs use the energy in sunlight to make food in the process of . Only certain organisms — such as plants, algae, and some bacteria — can make food through photosynthesis. Some photos...
are living things that cannot make their own food. Instead, they get their food by consuming other organisms, which is why they are also called . They may consume or other . Heterotrophs include all animals and fungi, as well as many single-celled organisms. In Figure 4.9.3, all of the organisms are consumers except for the grasses and phytoplankto...
is a with the chemical formula C6H12O6. It stores chemical in a concentrated, stable form. In your body, glucose is the form of energy that is carried in your blood and taken up by each of your trillions of . Glucose is the end product of , and it is the nearly universal food for life. In Figure 4.9.4, you can see how photosynthesis stores energy f...
If you remember from section 3.7 Nucleic Acids,(adenosine triphosphate) is the energy-carrying molecule that cells use to power most cellular processes (nerve impulse conduction, protein synthesis and active transport are good examples of cell processes that rely on ATP as their energy source). ATP is made during the first half of photosynthesis an...
Why do living things need glucose if ATP is the molecule that cells use for energy? Why don’t autotrophs just make ATP and be done with it? The answer is in the “packaging.” A molecule of glucose contains more chemical energy in a smaller “package” than a molecule of ATP. Glucose is also more stable than ATP. Therefore, glucose is better for storin...

All of the chemical reactions that take place inside cells, including those that use energy and those that release energy, are the cell’s metabolism. Figure 6.1.1 6.1. 1: Most energy comes from the sun, either directly or indirectly: Most life forms on earth get their energy from the sun. Plants use photosynthesis to capture sunlight, and ...
Virtually every task performed by living organisms requires energy. Organisms require energy to perform heavy labor and exercise, but humans also use considerable energy while thinking and even during sleep. Every organism’s living cells constantly use energy. Organisms import nutrients and other molecules.
Figure 9.1.1 9.1. 1: The structure of ATP shows the basic components of a two-ring adenine, five-carbon ribose sugar, and three phosphate groups. A large amount of energy is required in order to recharge a molecule of ADP into ATP. This energy is stored in the bond between the second and third phosphates. When this bond is broken, the energy is ...
Figure 4.9.2 Photosynthetic autotrophs, which make food using the energy in sunlight, include plants (left), algae (middle), and certain bacteria (right). Autotrophs are also called producers. They produce food not only for themselves, but for all other living things (known as consumers), as well. This is why autotrophs form the basis of food ...

Figure 2.2.1 2.2. 1. Ultimately, most life forms get their energy from the sun. Plants use photosynthesis to capture sunlight, and herbivores eat the plants to obtain energy. Carnivores eat the herbivores, and eventual decomposition of plant and animal material contributes to the nutrient pool.
