Glycolysis reactions take place in plasmids cell membrane cell wall cytoplasm TRUE ANSWER : ? YOUR ANSWER : ?
When living organisms are cooled below some critical body temperature, the metabolic reactions within their cells cease to function properly. This malfunction occurs because enzyme active sites become permanently bound to substrates the activation energy for the reaction is raised their enzymes lose the proper three-dimensional shape there is insufficient molecular motion for substrates to interact TRUE ANSWER : ? YOUR ANSWER : ?
The sugar which forms major component of nucleic acids is mannose galactose ribose maltose TRUE ANSWER : ? YOUR ANSWER : ?
The hormones, glucagon and epinephrine, stimulate glycogen breakdown to G-6-P only in the liver directly, by binding to glycogen phosphorylase using ATP as the phosphoryl donor indirectly, by first stimulating adenylate cyclase to make cAMP TRUE ANSWER : ? YOUR ANSWER : ?
The process not involved in the formation of glucose by gluconeo-genesis is the dephosphorylation of glucose-6-phosphate the conversion of lactate to pyruvate All of these the conversion of oxaloacetate to glucose TRUE ANSWER : ? YOUR ANSWER : ?
The conversion of pyruvate to oxaloacetate involves the fixation of carbon dioxide occurs in the mitochondria requires biotin all of the above TRUE ANSWER : ? YOUR ANSWER : ?
Metabolic reactions that break down complex molecules into smaller compounds, thereby releasing usable energy for the cell, are best described as biosynthetic catalytic catabolic photosynthetic TRUE ANSWER : ? YOUR ANSWER : ?
A common way that cells capture the energy released during the breakdown of large molecules is to add electrons to smaller, specialized molecules that can accept them. This process of electron acceptance is otherwise known as catalysis reduction biosynthesis metabolism TRUE ANSWER : ? YOUR ANSWER : ?
Which of the following statements about the energy needs of cells is false? Many cellular reactions have an associated activation energy Without a continuous input of energy, cell disorder will increase The laws of thermodynamics force cells to acquire energy The most usable energy for cells comes from the rapid combustion of glucose TRUE ANSWER : ? YOUR ANSWER : ?
