Question
,. Thylakoids, grana, and stroma are associated with the organelle called 21. Aquaporins are membrane structures that allow called 22. Cell motility requires the interaction of cytoskeleton with 23. The three types of fibers of eytoskeleton are 24. Centrioles are involve in cell 25. Cilia and flagella involve in to move in and out of cells by a process proteins he penetration of the hydropbobic interior of the lipid bilayer is dome by 27. To make the enzymes that are required for the setoxification of drugs and poisons, cells in the liver must have a large amount of the organelle known as 28. lons channels that open or close in response to stimuli are called 29. Large materials leave the cell specifically by 30. Any substance that binds specifically to receptor site of another molecule is called a 31. A reaction that absorbs free energy from its surrounding is said to be 32. A pathway that begins with a specifie molecule and is altered by a series of definedsteps, resang i certain product is called a 33. The activity of enzymes is affected by two environmental factors known as 34. Many enzymes require non-protein helpers known called 35. A metabolie pathway that is swiched off by the inhibitory binding of its product to an enzyme that acts for functioning early in the pathway is known as , the gain of electron is 36. The loss of electron from one substance is called Chapter 9 37. The first two stages of cellular respiration are 38. Before entering the mitochondria pyruvate must be converted into 39 Fermentation consists of 40. Two types of fermentations are plus reactions that regenerateExplanation / Answer
Answer- 20) Chloroplast
Explanation-
Chloroplast contains photosynthetic membranes arranged in flattened sacs known as Thylakoids.
The thylakoids are arranged in a stack like organisation known as Grana.
The regions between the grana are known as Stroma.
Answer-22) motor proteins.
Explanation-
Motor proteins are regarded as the driving force behind muscle contraction. These are also responsible for the active transport of most proteins and vesicles in the cytoplasm.
Answer-23) Microfilaments, intermediate filaments and microtubules.
Explanation-
The cytoskeleton is formed of three types of protein filaments. They are-
Actin filaments or microfilaments
Intermediate filaments
Microtubules.
Answer- 24) Division.
Explanation-
Centriole are cylindrical cell structures formed mainly of tubulin proteins. They are specialized for the organization of the mitotic spindle and completion of the cytokinesis.
Answer- 25) Movement
Explanation-
Cilia and flagella are involved in movement of move liquid past the cell surface.
