Sessile
Sessile means attached. So a sessile organism is attached to a substrate.
A substrate is a surface or substance in which an organism can attach itself to support its growth. A synonym for substrate is substratum.
Substrate has several meanings. One definition is the base on which something lives or is attached. For example the ocean floor is a substrate to many living things including kelp.
it means that it is prouducing
Sponges only stay in one spot because they are sessile. Sessile means that they are attached to a substrate and cannot move. Hope this helps!
Setae are attached to each annelid segment. These bristles provide traction for movement and help anchor the worm in the substrate.
No. Sponges are the simplest animals and they are aquatic and sessile (attached to a substrate). A slug is in the Phylum Mollusca in the Class Gastropoda.
"Adjoined" is a word that means attached at a base.
False. Low Km actually indicates a strong binding of the enzyme to the substrate, resulting in a high affinity and low velocity at low substrate concentrations. High Km means a weak binding of the enzyme to the substrate and requires higher substrate concentrations for the enzyme to achieve maximum velocity.
Enzyme-substrate specificity means that a substrate can fit into an enzyme similar to a key fitting into a lock. The active site of the enzyme is what determines its specificity. An enzyme can hence catalyze a reaction with a specific substrate, such as amylase catalyzing starch molecules. During these reactions, the substrate is held in a precise optimum position to create and break bonds, catalyzing the molecule.
No and, by all means, no. For each and every substrate there are enzymatically (repeatedly) produced products.
When they are adults, barnacles live attached headfirst to the substrate (rocks, wood, etc.) and stay in that spot for the rest of their lives.
