Q: 5: Which of the following best describes anabolic reactions?
Answer:
Energy-storing reactions which link simple molecules together to make complex ones
Explanation:
Anabolism or anabolic reactions comprise the process during which simpler molecules are joined or linked to form complex compounds. These reaction require the input of energy but ultimately that energy is stored in complex molecules for later use.
Organisms employ the reactions which absorb the energy in several reactions. and this absorbed energy is then stored for later use to perform various activities of the body.
For example: Photosynthesis is the common example during which energy from the sun is used to create sugar based molecules like sucrose and glucose. The formation of glucose is an anabolic process because it makes complex compound from simple compounds and stores energy in them which is later used to by plants to perform daily activities and work.

Q: 18: What are the folds of the inner membrane of mitochondria?
Answer:
Cristae
Explanation:
Cristea are the fodings present in inner mitochondrial membrane . The reason why there are called cristae came from Latin word crest that means wrinkled or irregular shape in a way that increases the surface area of the object.
If we look at cristea in mitochondria , its purpose is same, to provide a huge amount of surface area for the diverse types of reactions of cellular respiration that takes place in the inner mitochondrial membrane.
These folds not only enhance surface area but also support aerobic cellular respiration in a number of ways. there are large amount of proteins studded in cristaea like cytochromes and ATP synthases that make sure an efficient execution of the process of cellular respiration.

Q 13: Which statement correctly describe one similarity between cellular respiration and photosynthesis?
Answer:
Cellular respiration and photosynthesis both have water and carbon dioxide in the reactions
Explanation:
If we talk about the processes of photosynthesis and Cellular respiration both are almost exact opposite in nature. The products of cellular respiration are the reactants of photosynthesis and vice versa.
The sunlight in mandatory for the execution of photosynthesis however, cellular respiration depends on the supply of glucose and ultimate three phases (glycolysis, kreb cycle and electron transport chain) to transform the glucose in the usable energy reservoir ATP.
But still, when we look at the equations of cellular respiration and photosynthesis, we see something is common. And what is that common thing is, Cellular respiration and photosynthesis both have water and carbon dioxide in the reactions. (please see attached figure).
In cellular respiration, water and carbon dioxide are the products along with energy, while in photosynthesis water and carbon dioxide are the reactants.
Hope it helps!
A. The correct option is c.
B. The correct option is c.
C. The correct option is b.
Anabolic reactions are energy-storing reactions linking simple molecules to create complex ones. The folds of the inner membrane of mitochondria are called cristae. Cellular respiration and photosynthesis both involve water and carbon dioxide in their reactions.
The best description for anabolic reactions is option c. Anabolic reactions are energy-storing reactions which link simple molecules together to create more complex ones. They involve the formation of larger molecules from smaller ones. This process requires energy, often sourced from ATP molecules generated by catabolic reactions. Examples of anabolic reactions include the combination of monosaccharides to form polysaccharides, fatty acids to form triglycerides, amino acids to form proteins, and nucleotides to form nucleic acids.
The folds of the inner membrane of mitochondria are called cristae. These folds increase the surface area of the membrane, enabling a greater space for activities related to cellular respiration, such as the production of ATP.
A correct similarity between cellular respiration and photosynthesis is that both processes involve water and carbon dioxide in the reactions. These two processes are crucial for energy transfer in most life on Earth.

Answer:
Homologous chromosomes do not function the same in mitosis as they do in meiosis. Prior to every single mitotic division a cell undergoes, the chromosomes in the parent cell replicate themselves. The homologous chromosomes within the cell will ordinarily not pair up and undergo genetic recombination with each other.
Answer:
Telophase
Explanation:
In this phase, the chromosomes have moved to separate ends of the cell.

B-alcohol fermentation
C-citric acid cycle
D-electron transport chain
Answer:
The correct answer would be B-alcohol fermentation.
Alcohol fermentation or ethanol fermentation is a type of anaerobic respiration by which organism (such as yeast) convert sugar such as glucose, sucrose et cetera into ethanol and carbon dioxide in order to produce energy.
First, glucose is converted into 2 molecules of pyruvate by the process of glycolysis. It leads to the formation of 2 molecules of ATP (adenosine triphosphate) and 2 molecules of NADH.
Then, two molecules of pyruvate are converted into two molecules of acetaldehyde with the help of enzyme pyruvate decarboxylase. Two molecules of carbon dioxide are released as a byproduct.
Lastly, two molecules of acetaldehyde are converted into two molecules of ethanol with the help of enzyme alcohol dehydrogenase. It consumes two NADH and regenerates two NAD⁺ lost during the process of glycolysis.
Hence, the net gain of alcohol fermentation is two ATP.
Thus, we can say that ethanol is produced during alcohol fermentation.
During alcohol fermentation ethanol is produced.
Alcohol fermentation involves the break down of sugars in organisms such as yeast to form ethanol or alcohol, carbon dioxide and release energy.
