- What is an endergonic reaction?
- What is the solution? and why?
- What are membranes made up of?
- What is a substrate?
- What is ATP?
- a A specific reactant that an enzyme reacts on, fits into the active sight
- b Adenosine Triphosphate, powers nearly all forms of cellular work
- c A reaction that requires energy, its products have more energy than its reactants, energy is absorbed through surroundings as reaction occurs, energy stored in covalent bonds of product molecules
- d Enzymes, and Because enzymes act as biological catalysts that increases the rate of a reaction without itself being changed into a different molecule, smushes down energy barrier
- e Lipids, mostly phospholipids
5 Multiple choice questions
- The bonds that keep the three phosphates together are easily broken by hydrolysis, when the bond to the third group breaks the phosphate group leaves ATP which becomes ADP, and energy is released (?)
- signl transduction
- Most chemical reactions are organized into a series of steps, each catalyzed by an enzyme, to form certain product. If product is being over-made, then the product will act as an inhibitor to one of the enzymes in its pathway, called feedback inhibition (?)
- A chemical reaction that releases energy, reactants covalent bonds contain more energy than products
5 True/False questions
What is a hypertonic solution? → A solution whose pH is lower than that of the cells, cell gains water, pops
What is the active sight? → Requires that a cell expends energy to move molecules across membrane against concentration gradient, low to high concentration, ATP supplies energy for most active transport
How are enzymes like assembly lines? → A product from one catalyctic cycle becomes the substrate for the next, and so on down a chain of enzymes
How does facilitated diffusion work? → When molecules are too big to pass through membrane, so they go through protein to be able to get to the other side
What is energy coupling? → fluid mosaic of phospholipids and proteins
