⩥ How can ATP be synthesized without oxygen by fermentation?.
Answer: Fermentation and cellular respiration both begin the same way,
with glycolysis
⩥ ATP synthesized without oxygen by fermentation is also called?.
Answer: anaerobic respiration
⩥ Fermentation produces what in yeast cells?.
Answer: ethanol
⩥ Fermentation produces what in muscle cells?.
Answer: lactic acid
⩥ Cell reproduction can function in?.
Answer: reproduction, growth and development, and repair and renewal
⩥ DNA molecules are combined with proteins to form?.
Answer: chromatin, the substance of chromosomes
,⩥ The cell cycle is the?.
Answer: life of a full cell from the time it is first formed from dividing
parent cell until its own division into two cells
⩥ The cell cycle consists of?.
Answer: interphase and mitosis
⩥ DNA replicates when?.
Answer: before cell division (mitosis) during the S or synthesis phase of
interphase
⩥ A duplicated chromosome consists of two what?.
Answer: sister chromatids, joined at the centromere
⩥ Stages of Interphase.
Answer: G1 phase, Synthesis (S), and G2 phase
⩥ What cellular event occurs during G1 phase during interphase?.
Answer: the cell synthesizes mRNA and proteins
⩥ What cellular event occurs during Synthesis (S) during interphase?.
Answer: DNA replicates, producing two copies of each chromosome
, ⩥ What cellular event occurs during G2 phase during interphase?.
Answer: The organelles of the cell need to duplicate and the cell
prepares to enter mitosis
⩥ Cell division consists of?.
Answer: mitosis (division of the nucleus) and cytokinesis (division of
the cytoplasm)
⩥ How does the spindle form?.
Answer: spindle fibers form a protein structure that divides the genetic
material in a cell
⩥ The centrosome serves as the initiation site for the assembly of?.
Answer: microtubles, which grow outward from the centrosome toward
the periphery of the cell
⩥ What is the function of the spindle apparatus?.
Answer: to help separate sister chromatids in mitosis by attaching to the
centromere of a duplicated chromosome and pulling sister chromatids to
opposite poles of the cell
⩥ Four stages of mitosis.
Answer: prophase, metaphase, anaphase, and telophase
