Answer:
c. Oxidative phosphorylation yields a lot of ATP
Explanation:
Fermentation is an anaerobic process that takes place in the anaerobic bacteria to produce an energy molecule called ATP. The process of fermentation involves the breakdown of the glucose through glycolysis which produces 2 ATP molecules, NADH and Pyruvate molecules.
The process does not undergo further steps like the Citric acid cycle and the oxidative phosphorylation which forms the high number of ATP molecules.Since the organism which performs the fermentation does not undergo oxidative phosphorylation therefore the yield of ATP in the cell is very less.
Thus, Option-C is correct.

Answer: Interphase
The pericytes are in the interphase of the cell cycle. This is the phase of the cell cyclebetween each cell division and is the phase in which the cell obtains nutrients,grows, reads its DNA, and conducts other normal cell functions including thearrest of the growth of the pericytes that were treated so that they would notdivide but continue to function normally.
b. identical copies.
c. separated during mitosis.
d. made during the S phase.
e. All of the above.
Answer:
The correct answer is e. All of the above.
Explanation:
Sister chromatids are made during the synthesis phase of the cell cycle. In the synthesis phase, the homologous chromosomes get replicated and sister chromatids are produced so they are produced by duplication of chromosomes.
As sister chromatids are produced by replication, therefore, they are identical copies of parent chromosomes. These sister chromatids are joined to each other at centromere. They get separated during the anaphase of mitosis and moves to the opposite pole.
Therefore the right answer is e.
the G1 phase
the S phase.
O the G2 phase.
mitosis.
The G2 phase of the cell cycle is when rapid cell growth in preparation for cell division occurs. This is after DNA replication and before mitosis.
Rapid cell growth in preparation for cell division occurs during the G2 phase of the cell cycle. The cell cycle is a four-stage process consisting of the G1 phase (gap 1), the S phase (synthesis), the G2 phase (gap 2), and mitosis. During the G1 phase, cells grow and prepare for DNA replication which happens in the S phase. In the G2 phase, the cell experiences rapid growth in preparation for cell division, cell size increases dramatically, and proteins necessary for cell division are synthesised.

Answer: ADP provide the building block for ATP.
ATP is the energy source, the molecule that carry energy for cells activities.
Explanation:
Cellular respiration refers to processes in which carbohydrates or glucose is breakdown to release ATP, energy for cellular activities.
Adenosine diphosphate contain nucleotide, ribose and two phosphate group.
Adenosine triphosphates (ATP) contain nucleotide, ribose sugar and 3 phosphate groups. When ATP is used for cellular respiration, a great energy is use to build the bond holding 3 phosphate group in ATP and it require great energy to break it down,once it is broken down it releases energy.
ATP carries energy and release it in the cells,once it has release energy it becomes ADP.
During the process of cellular respiration, glucose provide energy to build ADP and additional phosphate group to form ATP.
Answer:
ATP is consumed in glycolysis to convert glucose to pyruvate, and produced in electron transport chain.
Explanation:
Cellular respiration consists of three parts in order: glycolysis, Krebs cycle, and electron transport chain.
Glycolysis involves total of 10 steps. Out of those, step 1 and 3 use ATP.
In step 1, hexokinase (HK) take a phosphate from ATP and add the phosphate to glucose to create glucose-6-phosphate. Because a phosphate is taken out, ATP becomes ADP.
In step 3, phosphofructokinase (PFK) take a phosphate from ATP and add the phosphate to fructose-6-phosphate to create fructose-1,6-bisphosphate.
In last step, ATP synthase uses the difference in hydrogen ion concentration to make ATP.
NADH catalyzes a series of reactions with several proteins to move hydrogen cations from mitochondrial matrix to intermembrane space. This creates a difference in hydrogen cation concentration.
The higher concentration in intermembrane space means hydrogen cations prefer to go back to mitochondrial matrix.
ATP synthase use this force to drive reaction that adds a phosphate to ADP to create ATP.
Answer:
The phase that not all cells enter, but is a phase where cells are not actively dividing is called the G0 or non-dividing phase.
Answer:
G₀ phase
Explanation:
Some types of cells divided slowly or not at all. These cells may exit the G₁ phase and enter a resting phase called G₀ phase. In G₀ phase, a cell is not actively preparing to divide. It's simply doing its job. For some cells, G₀ is a permanent state, while others may restart cell division given the right signals.
