Chapter 6.8, Problem 1TYK
Summary Introduction
Introduction:
When an individual consumes a meal, it contains carbohydrates, proteins, and fats in variable amounts. Approximately 90% of the dry weight of the diet is composed of these three components, which form an essential source of energy for the body.

- The glucose that enters the glycolysis pathway is split into two molecules of _____. a. ATP b. phosphate c. NADH d. pyruvatearrow_forwardCitric acid (or citrate) is an allosteric inhibitor of one of the first enzymes in glycolysis. How, in general, will it affect cellular respiration? Glycolysis will slow down when citric acid is abundant It will compete with glucose for the active site of the enzyme. It will stop the citric acid cycle when pyruvate is abundant. All of the abovearrow_forwardWhich of the following best describes the function of high energy phosphate compounds in metabolism? Allow for reduction potential needed to fuel biosynthesis Serves as an electron carrier Utilized for bond breaking to supply energy necessary for formation of ATP Allow oxidation to produce the maximal number of electronsarrow_forward
- Which of the following are true statements regarding cellular respiration? (Select all that apply) Group of answer choices Lactic acid fermentation is an aerobic process The final electron acceptor in the electron transport chain is oxygen Two ATP are produced in the citric acid cycle Glycolysis produces two net molecules of ATP Four ATP are produced in the Krebs cyclearrow_forwardWhich statement is true about anabolism and catabolism? The relationship between the two is not well understood Both make use of energy molecules and energy intermediates Anabolism always uses up too much energy Catabolism always produces too much energyarrow_forwardThe metabolic process that consumes more energy than any other is ?arrow_forward
- 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.arrow_forwardWhich 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.arrow_forwardATP is NOT directly produced by which of the following reactions? glycolysis the preparatory reaction the TCA cycle the electron transport chain and oxidative phosphorylation all of these produce ATP directlyarrow_forward
- Which of the following is NOT true of glycolysis? Select one: a. The pathway requires two molecules of ATP to get started catabolizing each molecule of glucose b. ADP is phosphorylated to ATP c. The pathway converts two molecules of NADH to NAD+ for each molecule of glucose that enters d. The pathway does not require oxygenarrow_forwardHow are ATP and NADH similar? They are interchangeable energy carriers, allowing the cell to use whichever molecule is in greatest abundance as a source of energy. They both act as electron carriers in the cell. Both compounds function as mobile energy carrier molecules in a cell. Both molecules are oxidized by molecular oxygen (O2) in reactions that release energy for use by the cell. Both ATP and NADH function as reducing agents in metabolic reactions.arrow_forwardThe TCA cycle is a metabolic process that, if happening undisturbed, starts at a certain place and returns to that same place indefinitely with the input of only 1 metabolite. What are the metabolic inputs and outputs (what goes in and what comes out) of the TCA cycle? Make sure you include numbers beginning with a single input molecule.arrow_forward
