Reactions that require energy are called Endothermic. The following reaction is between Sulphuric Acid (H2SO4) and Sodium Hydroxide (NaOH) to give Sodium Sulphate (Na2SO4) and water (H20):H2SO4 + 2NaOH --> Na2SO4 + 2H2O This equation is balanced. Counting the individual atoms on both...
An exergonic reaction a. requires more energy than it releases b. creates an explosion c. does not require energy to start d. releases more energy than it requires e. absorbs heat from the environment. All of the chemical reactions that occur in a cell are called a. homeostasis. b. meta...
State True or False and justify your answer: Krebs cycle and ETS both require oxygen to produce ATP. Capacitation involves the release of acrosomal enzymes that break down the zona pellucida. True False State true or false. Glycerol maintains glucose levels during rest. The...
In the early 21st century, the so-called “Ni active site” mechanism was proposed, and then turned out to be that the Fe element was the active site (“Fe active site” mechanism); while some recent findings propose that the synergistic effect of Ni and Fe sites are responsible for the...
Three examples of chemical reactions are: 1. Hydrogen peroxide being broken down into water and oxygen. 2. Macromolecules like proteins being broken down into the amino acids that make them up during digestion. 3. The formation of a disaccharide like sucrose, which results from the joining...
Various catalysts that contain oxygen vacancies (OVs) have been extensively researched through theoretical computations and experimental characterizations, given that OVs are the most common defects found in metal oxides. Shi et al. [80] constructed OVs on WO3 nanosheets by high-temperature post-treatme...
Chemicalhappen all around us every day. Whether it is a single replacement reaction in the battery of our flashlight, areaction that occurs when iron rusts in the presence of water and oxygen, or an acid-base reaction that happens when we eat – we experiencein almost everything we do. ...
Discovery of new types of reactions is essential to organic chemistry because it expands the scope of accessible molecular scaffolds and can enable more economical syntheses of existing structures. In this context, the so-called multicomponent reactions,
Some reactions require the input of energy to form new chemical bonds, this creating more complex molecules from simpler ones and storing free energy in those new chemical bonds. Those reactions are called ___. If electricity flows toward the negative...
Both photosynthesis and aerobic cellular respiration are examples of complex metabolic pathways, consisting of many linked chemical reactions that require enzymes to function. Briefly, explain two att Describe how energy is transferred from sunlight to ATP, from ATP to...
