All living things make enzymes, but we collect ours from microbes. That’s because microbes are very effective enzyme producers. We ferment carefully selected microbes in three-story tanks. The tanks contain high oxygen concentrations and a rich broth of nutrients. This is the fermentation medium....
substrate concentration, enzyme concentration, temperature, and pH. Each enzyme is uniquely optimized to function in its natural niche. For example, hydrolytic enzymes found in the lysosome function optimally at an acidic pH. By contrast, DNA ligase, on the other hand, functions best at a ...
Are there organelles found in epithelial cells? Which organelles are surrounded by two membranes? Which organelles in a cell contain hydrolytic enzymes? Which of the following is found in a plant cell but not in an animal cell? a. chloroplast b. Golgi apparatus c. mitochondrion d. ribosom...
What enzymes are used in translation? Peptidyl transferase is the main enzyme used in Translation. It is found in the ribosomes with an enzymatic activity that catalyzes the formation of a covalent peptide bond between the adjacent amino acids. What are the steps in translation? Translation is ...
The authors determined the sensitivity of algae to the presence of copper ions by measuring the inhibition of the production of certain cellular enzymes and showed, among other things, that the EC50 for Microcystis aeruginosa (Cyanobacteriota) in the community was significantly higher compared to ...
Very few of them eat any significant amount of animals, and those who do typically mostly stick to things like insects, not cows, pigs, and chickens. Jane Goodall, famous for her extensive study of apes while living with them, found that it was very rare for the primates she saw to ...

We don’t have the enzymes to break down fiber, but living inside of us inside of our large intestine, our colon, there’s this community of microorganisms, which we call the microbiome and their number is, um, quite staggering. So in this location, we have....
Just like plastic bags did, reusable bags multiply rapidly. Used for promotional (促销的) purposes and marketing of all kinds, reusable bags’ growing popularity means bags that have been used very little (or not at all) can be found piled in streets, in garbage cans, in city parks, and...
Some scientists call them “life force”. Enzymes are complex protein molecules found in every cell of your body. Molecules that accelerate, or catalyze, chemical reactions in our body. All living organisms (honey bees or humans) produce their own enzymes to provide the nutrients they need. Eve...
