How do enzymes increase the rate of a chemical reaction? Explain the role of hepatocytes in the metabolism of carbohydrates, proteins, and lipids. What enzymes are used in cellular respiration? Explain how enzymes are able to make reactions go faster by discussing activation energy and how enzymes...
Enzymes are a specialized type of protein, or a functional molecule made up of many amino acids linked together, that catalyze chemical reactions within living organisms. This means that they speed up chemical reactions, allowing metabolic processes to take place.Answer and Explanation...
2) and subsequent long-term LCFA metabolism, conditions similar to our fluorescence assays, were used to measure intracellular [14C]OA incorporation into more complex lipids in the presence of each inhibitor (Fig. 7). For this, [14C]OA was added to untreated and inhibitor-treated cells, which...
Antioxidant enzymes, with the capacity to catalyze reactions aimed to neutralize reactive oxygen species (ROS), are used as a defense mechanism to prevent or minimize cellular damage caused by ROS overproduction during stressful events (Lushchak, 2011; Pisoschi et al., 2021). In the present expe...
considerations, most notably reaction pathway dynamics and a role for non-biological catalysts, but their usefulness is supported by noting that nucleobases and fatty acids fall within a molecular weight range similar to that of abiotically plausible amino acids, while nucleotides and lipids do not ...
It also has a protective effect on DNA, proteins, or lipids [6,18,24]. It can catalyze the production of hydroxyl radicals in a Fenton-like reaction, unfortunately causing oxidative stress and cell damage, subsequently affecting protein aggregation processes or inflammation of the nervous system ...

Then the dry lipid films were hydrated and extruded nine times through 0.1 μm polycarbonate membranes using the Mini Extruder (Avanti Polar Lipids, Inc. USA) at 47 °C (DPPC liposomes) and 25 °C (DOPC liposomes). To remove any possible structural defects, the obtained liposomes were left...
Explain how enzymes are able to make reactions go faster by discussing activation energy and how enzymes interact with substrates. Explain the chemical digestion of lipids. Discuss the (A) enzymes involved, (B) sites of action, and (C) end-products of digestion. ...
