Question

drag the terms to their correct locations in these sentences. 1. there are three main types of cellular work: chemical, transport, and movement. most of this work is powered by the transfer of a phosphate group from one molecule to another in a process known as blank. 2. through energy coupling, cells use blank, or energy - releasing, reactions to drive blank, or energy - requiring, reactions. the molecule blank is the energy shuttle between these two types of reactions. 3. a specific blank speeds up each of a cells chemical reactions. 4. mechanisms such as blank enable precise control over a cells blank - all of its chemical reactions. terms: phosphorylation, enzyme, metabolism, endergonic, exergonic, feedback inhibition, atp

Explanation:

1. Phosphorylation is the transfer of a phosphate group between molecules and powers much cellular work.
2. Exergonic reactions release energy and are used to drive endergonic (energy - requiring) reactions, with ATP as the energy - shuttle molecule.
3. Enzymes are specific proteins that speed up chemical reactions in cells.
4. Feedback inhibition is a mechanism that allows for precise control over a cell's metabolism, which encompasses all its chemical reactions.

Answer:

1. phosphorylation
2. exergonic, endergonic, ATP
3. enzyme
4. feedback inhibition, metabolism
