Answer:

NO

Question 2: Homologous chromosomes ______.

Answer:

carry the same genes

Question 3: The cell cycle results in the production of

Answer:

two cells, each with the same amount of genetic material but with same genetic information.

Question 4: Centromere

Answer:

The fundamental chromosomal structure where proteins nucleate to form kinetochores that bind to spindle microtubules and mediate chromosome segregation during cell division

Question 5: Fermentation products in human cells

Answer:

Have lactic acid fermentation when the body needs lots of energy.Question 6: The energy gained from the electron transport chain across the mitochondrial

membrane can be used directly to generate:

Answer:

A proton (H+) concentration gradient

Question 7: Where does the citric acid cycle take place?

Answer:

Inside the matrix of the mitochondrion

Question 8: Chromatin

Answer:

A complex of DNA, protein, and RNA found in eukaryotic cells

Question 9: DNA is found in structures called ______.

Answer:

chromosomes

Question 10: Crossing Over

Answer:

Swapping of genetic material that occurs in the germ line. During meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another

Question 11: ATP Synthase

Answer:

A protein that catalyzes the formation of the energy storage molecules adenosine triphosphate using adenosine diphosphate and inorganic phosphate

Question 12: What are the reactants for the Electron Transport Chain process?

Answer:

10 NADH+2FADH+6 Oxygens+34 ADP+34 Phosphates

Question 13: Mitochondrial Matrix

Answer:

The site of the tricarboxylic acid cycle, a series of enzymatic reactions initiated by the conversion of pyruvate and fatty acids to acetyl coenzyme A.

Question 14: NAD+

Answer:

A molecule formed from vitamin B3 and ATP that acts as a carrier molecule for electrons and hydrogen.It then becomes NADH when two electrons and a hydrogen are added to the molecule.

Question 15: Sister Chromatids

Answer:

Refers to the identical copies formed by the DNA replication of a chromosome with both copies joined together by a common centromere

Question 16: A duplicated chromosome consists of two ______.

Answer:

sister chromatids Question 17: Upon completion of telophase, I and cytokinesis, there is(are) ______ cell(s).

Answer:

two haploid Question 18: Which of the following is an actual difference between mitosis and meiosis?

Answer:

A single cell is divided into two cells in mitosis and four cells in meiosis.

Question 19: Which of the following occurs during interphase?

Answer:

Chromosome duplication.

Question 20: What are the final/net output of glycolysis?

Answer:

2ATPs; 2NADH; 2 pyruvate

Question 21: Fermentation

Answer:

A metabolic process that produces chemical changes in organic substrates through the action of enzymes.

Question 22: What are the final outputs of the citric acid cycle?

Answer:

6CO2; 2ATP; 8NADH; 2FADH2

Question 23: Anaerobic

Answer:

Organisms are those that live an anoxic environment as one of them lacks oxygen

Question 24: The chromosomes of eukaryotic cells are found in the ______.

Answer:

nucleus

Question 25: Final Electron Acceptor

Answer:

The reduction to water is used as a vehicle by which to clear the mitochondrial chain of low energy

Question 26: Sexual intercourse in humans ______.

Answer:

allows a haploid sperm cell to fertilize a haploid egg cell Question 27: Which of the following is a characteristic seen in prophase I that does not occur in prophase II?

Answer:

Crossing over occurs

Question 28: Which are the phases of Glycolysis?

Answer:

Investment phase and harvest phase
