(a)
Interpretation:
The free energy source of skeletal muscles, eukaryotic cilia and bacterium flagellum should be compared.
Concept Introduction:
The energy in the biological system is present in the form of chemicals. Different types of cells use different energy sources.
(a)
Explanation of Solution
During the respiration, ATP molecules are formed in the eukaryotic cells. These ATP molecules stores the energy and they give out energy when hydrolyzed. The eukaryotic cells use ATP as their energy source. Hence, skeletal muscles and ciliause the energy derived from the hydrolysis of ATP.
The bacterium flagellum does not use ATP as an energy source. It uses proton motive force for the propulsion of the flagella. This work by the transportation of the hydrogen ions across the membrane and act like a battery.
(b)
Interpretation:
The components of skeletal muscles, eukaryotic cilia and bacterium flagellum should be compared.
Concept Introduction:
The cells are composed of different structure that helps them in carrying out different functions in the body. All the components of the cells are essential to carry out the physiological process for living.
(b)
Explanation of Solution
The skeletal muscles are made up of two types of filaments. These are actin and myosin. During skeletal muscle contraction, the actin filaments slide over the myosin head.
The eukaryotic cilia are made up of microtubules and dynein. The bacterium flagellum is made of motA, motB, FliG and other ancillary components.

- Efficiency of ATP Production in Muscle: The transformation of glucose to lactate in myocytes releases only about 7% of the free energy released when glucose is completely oxidized to CO2 and H2O. Does this mean that anaerobic glycolysis in muscle is a wasteful use of glucose? Explain.arrow_forwardBiochemical events in the synthesis of ATP: I. Subunits of ATP synthase chages in conformation and twists/rotates as H+ moves through it II. H+ gradient is the driving force (through the ATP synthase) to form ATP from ADP + Pi. III. H+ moving across the membrane through ATP synthase rotates its ring of c subunits II and III only I, II, III I and II only I and III onlyarrow_forwardModified TRUE or FALSE. Write the word TRUE if the statement is correct. If the statement is false, write the incorrect underlined word/s and indicate the correct word/s to make the statement true. The Michaelis-Menten Constant (Km) of an enzyme is equal to the enzyme concentration at which the initial velocity of the reaction is one half of maximum velocity (Vmax).arrow_forward
