Describe how Microfilaments is involved in fertility (either directly or indirectly), include 5 roles for this type of cytoskeletal fiber.

name the enzymes of matrix biosynthesis, which should correct violations of the DNA structure in the norm, indicate its localization, connection with the phases of the cell cycle, energy sources

Describe how Microtubules is involved in fertility (either directly or indirectly), include 2 roles for this type of cytoskeletal fiber.

Determine whether the statement is true or false. 1. Membrane proteins may act as transporter, channel, receptors and cell identity markers. 2. Nucleolus contain digestive enzyme that aid cell renewal. 3. The vacuoles in animals are more common and bigger than with plants and bacteria. 4. Chlorophyll is the solar energy-capturing organelle derived from photosynthetic bacteria. 5. Proteins embedded on the plasma membrane may also transport some molecules to and outside the cell. 6. Nuclear envelope is a double membrane with pores that separates the nucleus from the rest of the cell. 7. Eukaryotic cells are considered the first cell type on Earth and are the cell type of bacteria and archaea. 8. Cell wall surrounds plasma membrane which is common among plants, fungi and many protists. 9. Ribosomes direct the synthesis of RNA. 10. The cytoskeleton is a network of interconnected membranes that helps move substances within the cell.

Explain/compare the following:totipotent vs pluripotent vs multipotent cells

TELOPHASE This stage shows the end of Telophase AFTER cytokinesis has occurred • Nuclear membrane reformed in each cell • Nucleolus reformed in each cell • Centrioles present in cells at one end Two new daughter cells with same # of chromosomes: 46 single stranded chromosomes in each nucleus Daughter Cell Diploid cell 2n = Daughter cell Diploid cell 2n =

For each of the following statements, indicate whether it is true or false [Select] [Select] the plasma membrane continuously without any regulation. [Select] Cytoplasmic [Ca²+] has no role in regulating secretion. [Select] constitutive secretion. All secretory vesicles bud off the trans Golgi network and fuse with [Ca²+] increases, which eventually leads to the elevation of the fertilization envelop. ✓ During fertilization, when the sperm fuses with the egg, cytoplasmic The release of neurotransmitter by a nerve cell is a form of

1)microtubules elongate preferentially from plus end (true or false ) 2) catastrophin proteins hasten the catastrophic depolymerization of microtubules (true or false )
