When ATP is broken down, energy is released. This energy is used by the cell to do work. For example, in the mechanical work of muscle contraction, ATP supplies energy to move the contractile muscle proteins.

- Why Organisms Need Both Glucose and ATP
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...

Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.
- Depending on your teacher or textbook, the amount of ATP produced during aerobic respiration is either 30-32 or 36-38. Both are technically correct...
- Water is indeed used in cellular respiration. During Krebs cycle one molecule reacts with fumarate forming malate. But it is also produced during E...
- it can become part of sweat or urine and leave the body, but it can also just join the multitude of water already in your body and go wherever the...
- Breathing has to do with taking in oxygen. Cellular respiration is where glucose is broken down into its chemical potential energy and stored as AT...
- Venus flytraps use enzymes to break down their catch, and use it for nitrogen, since they are deprived, and produce glucose the same way, just not...
- Fermentation is the anaerobic process of producing ATP, so yes, it counts as cellular respiration. However, it is anaerobic, meaning it does not us...

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, adaptation, growth and development, homeostasis, energy processing, and evolution. When viewed together, these characteristics serve to define life.
Coniine exposure affects the periphery, blocking neuromuscular transmission onto skeletal and smooth muscles. As little as 0.5–1 g of coniine (about the same weight as a paperclip) is lethal for humans, and symptoms include drowsiness, burning of the mouth and throat, gradual asphyxia, ascending paralysis, and death.
Coniine is a poisonous chemical compound, an alkaloid present in and isolable from poison hemlock ( Conium maculatum ), where its presence has been a source of significant economic, medical, and historico-cultural interest; coniine is also produced by the yellow pitcher plant ( Sarracenia flava ), and fool's parsley ( Aethusa cynapium ).

All living things carry out 7 basic functions integral to survival: Metabolism – Living things undertake essential chemical reactions. Reproduction – Living things produce offspring, either sexually or asexually. Sensitivity – Living things are responsive to internal and external stimuli.
