It is INCORRECT to affirm that: Chemical reactions called oxidation-reduction reactions are essential to life since they are the reactions that break down food molecules to produce energy. Oxidation refers to the loss of electrons; in this process the oxidized substance releases energy. Reduction refers to the gain of electrons; in this process, the reduced substance gains energy. Oxidation-reduction reactions do not always parallel; when one substance is oxidized, another also can be oxidized at the same time.

Which of the following is true of metabolism? A. Degradative reactions require an input of energy. B. Synthetic pathways are anabolic. C. Catabolism and anabolism are linked by O2. D. Catabolic reactions require the breakdown of ATP, and anabolic reactions generate ATP.
Your body stores energy in the form of fat and other organic molecules. When your body needs extra energy, it breaks apart the molecules of fat to release that energy (sometimes called "burning fat"). That energy is used to power cellular reactions or is lost as heat. The total amount of energy used by your body or lost as heat equals the amount of energy the molecules of fat originally stored before breaking apart. This process is an example of the _________law of thermodynamics. A. first B. second
The following speaks true of metabolism EXCEPT* Property consistent to all organisms ranging from prokaryotes to the human organism. Sum total reactions in the body Metabolic reactions contribute to homeostasis by harvesting chemical energy Metabolic reactions are entirely exergonic reactions Which of the following best characterizes ANABOLISM?* It is largely exergonic reaction because it releases energy in the form of heat It is involved in the building up process from polymers to monomers Reactions are usually oxidative and degradative Plays a crucial role in growth repair and maintenance of body structures The oxidation of glucose to produce ATP is also known as cellular respiration, and it involves four sets of reactions, which of the following is not part of the four sets of reactions?* Formation of pyruvic acid Glycolysis Formation of acetyl coenzyme A Citric Acid cycle Which of the following is an inaccurate statement?* fatty acids and glycerol are the building…
"Animals and plants use oxidation to extract energy from the food molecules", is true or false.
Each ATP molecule contains about 1% of the amount of chemical energy available from the complete oxidation of a single glucose molecule. Cellular respiration produces about 38 ATP from one glucose molecule. What happens to the rest of the energy in glucose? It is stored as fat. It is converted to heat. It is used to make water from hydrogen ions and oxygen. It is released as carbon dioxide and water It is converted to starch.
The image shows the electron transport chain and ATP synthesis during cellular respiration within a eukaryotic cell. The reaction shows the conversion of glucose into ATP and heat during eukaryotic cellular respiration. Which of the following is true regarding specialized cellular respiration occurring in newborns and hibernating mammals to maintain body temperature? Additional molecules of glucose are oxidized to generate the additional body heat required for human infants and hibernating mammals. The cellular efficiency of ATP synthesis increases to generate the additional body heat required for human infants and hibernating mammals. The cellular efficiency of the electron transport chain increases to generate the additional body heat required for human infants and hibernating mammals. The electron transport chain and proton gradient efficiency are maintained without ATP synthesis to generate the additional body heat required for human infants and hibernating mammals.
For each of the following pairs of molecules, indicate which member of the pair is reduced and which is oxidized, and which has more chemical energy and which has less chemical energy: NAD1/NADH; FAD/FADH2;CO2/C6H12O6.
Which of the following statements concerning glycolysis is incorrect? Group of answer choices It is an oxidation process in which no molecular oxygen is used. All reactions take place in the cytosol of a cell. There are two stages, each of which involves a series of five reactions. No correct response.
What impact might a substance that blocks the binding of NAD+ to electrons have on cellular respiration and metabolism (weight). The substance has no effect on hunger and only impacts the rate of cellular respiration and the fuel sources already available in the body! Group of answer choices Will promote weight loss because cellular respiration would increase because more fuel would need to be metabolized to generate the needed ATP Will promote weight loss because cellular respiration would slow down because there is nowhere for the electrons to go Will promote weight gain because cellular respiration would slow down because there is nowhere for the electrons to go Will promote weight gain because cellular respiration would increase because more fuel would need to be metabolized to generate the needed ATP
Which of the following describes the critical role that ATP plays in cellular metabolism? ATP serves an energy shuttle in the cell, coupling exergonic anf exergonic reactions. The terminal phosphate group of ATP is attached by a particular strong covalent bond that releases extra energy when broken. It is one of the four building blocks for RNA synthesis. Hydrolysis of ATP provides energy to drive exergonic reactions in the cell.
