Q

An animal cell that lack ribosomes are called transitional elements where transport vesicles from to carry newly made products to the golgi

A

Smooth ER

17
Q

Smooth ER activities also include ?

A

1.Synthesis of of lipids& steroid hormones. 2.Control of muscle cell Ca++ release& contraction. 3.Breakdown of lipid-soluble toxins by the liver

18
Q

Is a single membrane bound structure that forms a stack of interconnected vesicles

A

Golgi apparatus

19
Q

It’s function is the packaging/delivery of enzymes& hormones within the cell.

A

Golgi apparatus

20
Q

Vesicles pinch off and deliver their contents to?

A

Lysosomes,peroxisomes, secretory visicles

21
Q

Are vesicles filled with hydrolytic enzymes

A

Lysosomes

22
Q

A fact: release of lysosomal contents to the cytosol can result in cell death (necrosis)

A

True

23
Q

Are vesicles filled with enzymes that break down hydrogen peroxide to oxygen and water

A

Peroxisomes

24
Q

This enzymatic activity protects cells from excessive oxidative products made by the cell

A

Peroxisomes

25
Q

Are packaged into? In the golgi. Once formed the vesicles are transferred to the cell surface where they release their contents to the cell’s exterior

A

Secretory vesicles

26
Q

Animal ? Are the small membrane bound sacs. play roles in -intracellular digestion -release of cellular waste products

A

Vacuoles

27
Q

Composed of a network of three primary protein filaments 1.microtubules 2.microfilaments 3.intermediate fibers

A

Cytoskeleton

28
Q

Cytoskeleton functions include?

A

1.maintenance of cell shape&motility 2.internal movement of cell organelles 3.cell division

29
Q

The centrosome has a pair of centrioles the centrosome makes microtubules at cell division:1.the centrioles replicate. 2.the centrosome divides into two 3.the resulting two centrosomes move to opposite poles

A

Centrosome

30
Q

A fact:the spindle forms from the centrioles and participates in chromosome separation

A

True: centrosome

31
Q

The centrioles are part of the cytoskeleton. There are two perpendicularly arranged centrioles within the centrosome. Each centrioles is a ring of nine groups of threr fused microtubules per group

A

Centrioles

32
Q

Are the cellular power centers making usable energy (as ATP) from sugar& oxygen

A

Mitochondria

33
Q

This process occurs on the convoluted inner mitochondrial surface (cristae). The resulting ATP is used for activities including 1.growth/cell division 2.protein production 3.motion

A

A fact about mitochondria
