Answer key for this workbook.?

Why can't living cells use heat to provide the activation energy for their reactions? Heat is not readily available to all living cells2. Heat at excessive amounts denatures proteins3. When a critical point of heat level is reached, the proteins and cell can lose their function4. Heat doesn't provide the activation energy for their reactions A 1 and 4 B 2 and 4 C 3 and 4 D 2 and 3 E 1 and 3.

Living cells can rely on high levels of heat as a source of activation energy. Defined, a substrate is: A The reactant that an enzyme acts on when it catalyzes a chemical reaction B The product that an enzyme acts on when it catalyzes a chemical reaction C A and B D None of the above.

The substrate binds to a particular site on the enzyme to which it is attracted. The substrate and active site must contain distinctive shapes for binding to occur.Click here to go back to the main critical thinking page. Scroll down to see all choices.

This page book highlights vocabulary and notation, and has examples from the history of math. What makes this book unique and different from other algebra textbooks is that it is built from the experiences of an award-winning algebra teacher with more than 30 years of teaching experience.

Many textbooks are written by a committee of authors, and many of those authors have little experience teaching beginning algebra students in middle school or high school. It helps students see the connection between mathematics that they already know and algebra, so that learning algebra becomes easier and less abstract.

The catalyst increases the speed of the chemical reaction. The catalysis does not alter the state of the energy of the reagents and products of a chemical reaction.

Only the energy necessary for the reaction to occur, that is, the activation energy, is altered. Enzymes are proteins that are catalysts of chemical reactions. Chemistry shows us that catalysts are non-consumable substances that reduce the activation energy necessary for a chemical reaction to occur. Enzymes are highly specific to the reactions they catalyze. They are of vital importance for life because most of the chemical reactions in cells and tissues are catalyzed by enzymes.

Without enzyme action, those reactions would not occur or would not happen with the required speed for the biological processes in which they are involved. Enzymes have spatial binding sites to attach to their substrate. These sites are called the activation centers of the enzyme. Substrates bind to these centers, forming the enzyme-substrate complex.

There are two main models that explain the formation of the enzyme-substrate complex: the lock and key model and the induced fit model. In the lock and key model, the enzyme has a region with a specific spatial conformation for the binding of the substrate.

In the induced fit model, the binding of the substrate induces a change in the spatial configuration of the enzyme to make the substrate fit. The enzyme possibly works as like a test tube within which reagents meet to form products. This is one possible hypothesis. The substrate binds to the enzyme at the activation centers.

These are specific three-dimensional sites and therefore they depend on the protein's tertiary and quaternary structures. The primary and secondary structures, however, condition the other structures, and consequently are equally important. Select any question to share it on FB or Twitter. Just select or double-click a question to share.

Challenge your Facebook and Twitter friends. The activation center is a region of the enzyme produced by its spatial conformation to which the substrate binds. In the lock and key model, the activation center is the lock and the substrate is the key. Enzyme action is highly specific because only the specific substrates of an enzyme bind to the activation center of that enzyme. Each enzyme generally catalyzes only one specific chemical reaction.

According to the lock and key, enzyme functionality depends entirely on the integrity of the activation center, a molecular region with specific spatial characteristics.

After denaturation, the spatial conformation of the protein is modified, the activation center is destroyed and the enzyme loses its catalytic activity.
