galina1969 [7]

Answer;

-The reactions will be driven to the right

Explanation;

Volcanic eruptions are known to throw huge amounts of gas into the atmosphere, including carbon dioxide that are thought to increase global warming.

They spew lava, carbon dioxide and other elements into the deep oceans. The carbon gets trapped in circulating water, cycled to different regions of the ocean, where it gets caught up in upwelling currents and emitted to the atmosphere.The process can take up to 2,000 years and adds a fraction of the 88 million metric tons of carbon belched out by the volcanoes to the atmosphere.

Ugo [173]

During an enzymatic reaction, a molecule of substrate binds to the enzyme and is broken down into one or more molecules of product , which are released.

<h3>What is substrate and product ?</h3>

While products can be produced at the end of the reaction, substrates are the reaction's initial raw material. The distinction between a substrate and a product is that a substrate is the substance used to initiate a chemical reaction, whereas a product is the compound formed when the reaction is finished.

<h3>What do you mean by enzymatic reaction ?</h3>

In an enzyme reaction, the free enzyme E binds to its substrate S to form the enzyme-substrate complex (C1), which is then catalyzed into the enzyme-product complex (C2), from which the free enzyme and product P are released: S + E ↔ C1 ↔ C2 → P + E. This is known as the "lock-and-key" model in enzymatic reactions. The great majority of cellular reactions are represented by this paradigm.

Thus from the above conclusion we can say that during an enzymatic reaction, a molecule of substrate binds to the enzyme and is broken down into one or more molecules of product , which are released.
