1.) Which compound makes energy available for direct use in the cell?  

Pyruvic acid Ribulose diphosphate (RDP) Phosphoglyceric acid (PGA) Adenosine triphosphate (ATP) Deoxyriboneucleic acid (DNA)

2) Aerobic and anaerobic respiration have one of the following in common?

Carbon dioxide and water are released. Occur in photosynthesizing cells Use carbon dioxide Release energy from food Are the reverse process of photosynthesis

3) Which one of the following reactions in the human body supplies the most energy for metabolic processes?

Sucrose -> glucose + water Pyruvic acid -> carbon dioxide + water Amino acids -> glucose + urea Glucose -> pyruvic acid + carbon dioxide Adenosine diphosphate + a phosphate group -> adenosine triphosphate

4) Which of the following is the best description of cellular respiration?

The muscular movement of the chest to take in oxygen. The oxidation of sugar - a process that occurs only in animals The release of energy from energy-rich compounds in plants and animals The exchange of oxygen and carbon-dioxide in the respiratory organs The intake of oxygen and the liberation of carbon dioxide by animals and the intake of carbon dioxide

5)Which of the following is an end product or products of anaerobic respiration in plants and animals?

Alcohol only Lactic acid only Alcohol and lactic acid Alcohol, lactic acid and oxygen Alcohol, lactic acid and carbon dioxide

6)Which of the following compounds contain the most energy per molecule?

Pyuruvic acid Glucose Ethanol (ethyl acid) ADP ATP

7)Which one of the following is the first step during aerobic respiration of a glucose molecule?

Oxidation of pyruvic acid Uptake of oxygen Phosphorylation of glucose Release of energy Formation of ATP

8) What is the name of the fold in the block pointed to by A?

Villi Micro villi Crista Endoplasmic Reticulum Endometrium

9) Which of the following processes takes place in the place pointed to by A?

Glycolysis Electron Transport chain The Krebs cycle Deamination Gaseos exchange

10) Which of these is the most likely to cause oxygen debt?

Very hard exercise Tiredness Not enough glucose in blood Absolute rest Steady regular exercise for a long period of time

11) For which of these processes is the large surface area of the cristae of the mitochondrion important?

Making proteins Enzyme reactions of glycolysis Oxidative phosphorylation Krebs Cycle Rapid diffusion of gases

12) In anaerobic respiration the hydrogen acceped by NAD is later added to..

Lactic acid Pyruvic acid Alcohol Citric acid ATP

13) Which of these is incorrect about the chemical changes that happen when some muscle is contracting rapidly and often?

Increased uptake of oxygen Increased release of carbon dioxide The formation of acid Chemical changes to some phosphate compounds A rise in the carbohydrate level

14) Which of these comparisons of the end products of aerobic and anerobic respiration of one glucose molecule is untrue?

Aerobic end-product                             Anerobic end-product

Many ATP molecules made <=> fewer molecules made Cannot be used as energy source <=> can be used as a fuel Fewer water molecules <=> more water molecules More carbon dioxide molecules <=> fewer carbon dioxide molecules The same in animals and plants <=> different in animals and plants

15) Which of the following is used as well as made during glycolysis?

Oxygen Hydrogen ATP Carbon dioxide Glucose
