Explanation: Natural gas is a limited resource. Natural gas is in the fossil fuel family and it's underground. I think it's pretty plentiful meaning that there's a lot in the United States of America. Many people use it for home heating instead of heating oil. Some people have oil trucks where the oil truck has to come and deliver oil to them.
So, natural gas is limited resource because it's a fossil fuel and it gives off emissions. It's in the ground and it's from years of decaying stuff. It's not like solar or wind power, it's a limited resource.
The formation of macromolecules from triose phosphate is likely anabolic and would be coupled to ATP -> ADP.
Anabolic is a group of metabolic pathways that builds compounds out of smaller building blocks. These reactions, which are often referred to as endergonic processes, demand energy. Catabolism is the breakdown component of metabolism, whereas anabolism is the building component. Typically, anabolism and biosynthesis go hand in hand. Anabolism can be seen in the growth of muscle mass and the mineralization and development of bones. Proteins are broken down into amino acids during catabolic events, as are glycogen and triglycerides into glucose and fatty acids, respectively. Fundamentally, catabolism entails disassembling complex molecules to produce energy that may be utilised by the organism. By building larger, more complex molecules from smaller, simpler ones, anabolism is the exact reverse of catabolism. The body typically stores them for later use.
