How many phosphate molecules will be released into the cytoplasm from the conversion of 6 ATP molecules into 6 ADP molecules?

6

The reactants for a biochemical reaction are C6H12O6 + 6O2. What will be the products for this reaction, and where does the reaction take place?

6CO2 + 6H2O + energy; mitochondria

Which statement best describes photosynthesis and respiration? A. Autotrophs carry out photosynthesis, while autotrophs and heterotrophs carry out respiration. B. Autotrophs and heterotrophs both carry out photosynthesis and then respiration. C. In autotrophs, photosynthesis requires oxygen, and respiration requires carbon dioxide. D. Only autotrophs carry out photosynthesis, while only heterotrophs carry out respiration.

A. Autotrophs carry out photosynthesis, while autotrophs and heterotrophs carry out respiration.

Which substances are produced during glycolysis?

ATP and pyruvate acid

Considering that in aerobic respiration 38 ATP are created and in anaerobic respiration 2 are created, are large organisms more likely to be aerobic or anaerobic?

Aerobic because it takes more energy for a larger body to function.

Which statement is an accurate comparison of aerobic and anaerobic respiration in humans?

Aerobic respiration requires enzymes to facilitate its biochemical reactions, whereas anaerobic respiration does not use enzymes.

Which statement describes the key ways cellular respiration and photosynthesis are similar?

Both processes involve the cycling of organic and inorganic compounds.

Which situation will most likely cause increased production of lactic acid in cells? A. eating a large meal B. lifting a heavy object C. running for several hours D. sitting still for a long period of time

C. running for several hours

Which balanced chemical equation represents aerobic cellular respiration?

C6H12O6 + 6O2 --> 6CO2 + 6H2O

What gas, captured in the glass tube, is produced by yeast?

Carbon dioxide

Which statement best describes cellular respiration? A. It is the metabolism of water into oxygen and hydrogen. B. It is the intake of oxygen and release of carbon dioxide. C. It is the creation of energy from oxygen and water. D. It is the conversion of food energy into a more usable form.

D. It is the conversion of food energy into a more usable form.

Which statement explains how food provides energy to cells?

Food stores energy which is used to form adenosine triphosphate (ATP), a molecule that provides energy to cells.

Which equation best represents the aerobic respiration reaction?

Glucose + Oxygen → Carbon Dioxide + Water + ATP

What is the function of the mitochondria shown?

It is the site of aerobic respiration in eukaryotes.

Rotenone is a toxic substance derived from several tropical and subtropical plants. It is used as a pesticide to control certain populations of insects and fish. Rotenone interferes with the electron transport chain in the mitochondria of the cells of those organisms. If the electron transport chain does not function properly, how does that impact the cells?

It prevents the production of ATP during aerobic respiration.

Why is the electron transport chain an important step in aerobic respiration?

It produces most of the ATP molecules.

Which part of aerobic respiration requires oxygen in order to take place?

Krebs cycle

Which would most likely occur if the mitochondria were damaged in an animal cell?

The cell would be unable to produce ATP for energy.

How are the reactions of photosynthesis and cellular respiration interconnected?

The reactions are opposites of one another, each using the products of the other as reactants.

What chemical reaction is represented? C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy

aerobic respiration

Which organisms carry out cellular respiration?

all living things

A baker uses yeast to make bread dough then lets it sit for one hour. During that time the dough doubles in size. What process is responsible for this effect?

anaerobic respiration

When athletes run long distances, their muscles become fatigued due to a lack of oxygen. Which process helps athletes generate more energy to continue running?

anaerobic respiration

When yeast ferments and breaks down sugar in the bread-making process, what is produced by the yeast that makes the bread rise?

carbon dioxide

At which location in this cell would glycolysis occur?

cytoplasm

If all the mitochondria of a cell are damaged, then the concentration of which substance builds up in the cell?

glucose

The greatest production of energy in a cell will result in the formation of which molecules?

glycerol and fatty acids

Which part of cellular respiration takes place in the cytoplasm?

glycolysis

Which part of the cellular respiration process generally produces the greatest amount of energy in the form of ATP?

glycolysis

While performing strenuous exercise, a person may experience a temporary shortage of oxygen. As a result, anaerobic respiration supplies the required energy. What is an end product that will build up in the person's muscles?

lactic acid

A doctor sees a patient who has kidney failure, lack of motor coordination, and a poorly functioning nervous system. After testing, the doctor finds that these symptoms are all related to a chronic lack of energy in some of the patient's cells. The doctor diagnoses a metabolic disorder known as Leigh's disease. Based on this evidence, a malfunction in what organelle is most likely responsible for Leigh's disease?

mitochondria

Which organelle and function are accurately paired for the process of cellular respiration?

mitochondria: converts the energy in glucose into cellular energy

Which molecule is critical for getting the maximum energy yield per molecule of glucose from cellular respiration?

oxygen

Which process is correctly aligned with the organelle in which it occurs?

photosynthesis: chloroplast respiration: mitochondria

What compound, indicated by the letter X in this diagram, is produced by glycolysis and transported into the mitochondrion prior to the Krebs cycle?

pyruvic acid

Which factor would have the greatest effect on the cellular respiration rate of an animal?

the amount of oxygen available

Cellular respiration is a biochemical process in which cells use food energy to provide energy for cell processes. What is the first stage of cellular respiration?

the breakdown of a glucose molecule into pyruvic acid and ATP

True or False: In both alcoholic and lactic acid fermentation, both produce carbon dioxide.
