Enzymes remain unaltered during the entire reaction and are required in a small amount Enzymes have specificity to their substrate and can catalyze about 1-10000 molecules per substrate. The activity of enzymes can be influenced by the concentration of enzyme, and substrate, the temperature, and...
they also effectively remove dissolved organic matter (DOM) from seawater10,12. Sponge grounds of Arctic-Boreal regions are often dominated by large high-microbial abundance species (HMAs, i.e., sponge species which host highly diverse and dense microbial communities in their tissue) of the genus...
Bile acids play an important role in intestinal absorption of lipids30, but also may promote protein denaturation and potentiate the activity of digestive proteases31,32. Post-prandial free bile acid concentrations in the human small intestine reach up to 10 mM6. To investigate the effect of b...
Which cell organelle makes the digestive enzymes present in lysosomes? Which organelle is responsible for protein synthesis in the cell? (a) Golgi apparatus (b) ribosomes (c) mitochondria (d) nucleus. Which organelle is referred to as the cell powerhouse? What are the functions of organelles?
The Central Arctic Ocean is one of the most oligotrophic oceans on Earth because of its sea-ice cover and short productive season. Nonetheless, across the peaks of extinct volcanic seamounts of the Langseth Ridge (87°N, 61°E), we observe a surprisingly
only 10 to 20 days after meal, suggesting that the former might play a role in processes related to early digestion [116]. The midgut transcriptome ofR. prolixusshows that transcripts from digestive enzymes are significantly well expressed, with a predominance of cysteine and aspartic proteases [...
dependent oxidation of PE could thus provide a suitable substrate for further biological attack by causing the scission of the long polymer chains into smaller molecules that could then be metabolized and assimilated along the insect’s digestive system (by the microbiome and/or by the insect’s ...
