Explanation:
Why is NAD+ so important if the cell takes the anaerobic pathway, so glycolysis to fermentation? Does the atp made in glycolysis depend on the NAD+ conversion to NADH in the first step? I am confused on why NAD+ is so important to atp production
Answers
Answer:
NAD+ (nicotinamide adenine dinucleotide) is indeed crucial for ATP production, even in anaerobic pathways such as glycolysis followed by fermentation. Allow me to explain the significance of NAD+ and its role in ATP production.
During glycolysis, glucose is broken down into pyruvate, producing a small amount of ATP and NADH. The conversion of NAD+ to NADH occurs during the oxidation of certain molecules, including glucose, in the pathway. This conversion is essential because NADH carries high-energy electrons that can be used in subsequent steps to generate more ATP.
In aerobic respiration, NADH is further utilized in the electron transport chain (ETC) within the mitochondria. The ETC transfers electrons from NADH to oxygen, generating a significant amount of ATP through oxidative phosphorylation. However, in anaerobic conditions where oxygen is limited, like during fermentation, the ETC cannot function.
Here's where NAD+ becomes critical. In order to keep glycolysis running and continue generating ATP, the NADH produced during glycolysis must be converted back to NAD+. This allows glycolysis to continue producing ATP, even without the presence of oxygen. Without a mechanism to regenerate NAD+, glycolysis would halt due to a lack of NAD+, leading to a severe reduction in ATP production.
Fermentation pathways differ depending on the organism, but they all involve the regeneration of NAD+. For example, in lactic acid fermentation, pyruvate is converted into lactate, which involves the transfer of electrons from NADH to pyruvate, regenerating NAD+. Similarly, in alcoholic fermentation, pyruvate is converted into ethanol, again regenerating NAD+.
In summary, NAD+ is essential in anaerobic ATP production because it serves as a coenzyme that accepts electrons and facilitates the conversion of NADH back to NAD+. By regenerating NAD+, cells can sustain glycolysis and continue producing ATP, even in the absence of oxygen.

D. Given that the diameter of the field of view of a light microscope is 2000um. Calculate the size of a cell in mm if 10 cells occupy the diameter of the field of view
Answers
Answer:
Explanation:
If 10 cells occupy the diameter of the field of view of a light microscope, then the size of one cell is equal to the diameter of the field of view divided by 10.
Diameter of field of view = 2000um = 2mm (since 1mm = 1000um)
Size of one cell = (diameter of field of view) / 10 = 2mm / 10 = 0.2mm
Therefore, the size of a cell is 0.2 mm.

feedback mechanisms and homeostasis?
A. Feedback mechanisms are the organism's response to changing
conditions. They keep working until internal conditions return to
normal.
B. Feedback mechanisms counteract homeostasis.
C. Feedback mechanisms have no relationship to homeostasis.
D. A feedback mechanism is initiated when conditions are stable for
too long. They work until the organism wakes up and begins to
move around.
Answers
The correct answer is A. Feedback mechanisms and homeostasis are closely related in that feedback mechanisms help to maintain homeostasis in living organisms. (option-a)
Homeostasis is the process of maintaining a stable internal environment despite external changes. Feedback mechanisms are the physiological responses of an organism to maintain this stability. For example, if the body temperature drops, the feedback mechanism in the body responds by shivering to generate heat and maintain the internal temperature. Similarly, if the body temperature rises, the feedback mechanism in the body responds by sweating to cool down and maintain the internal temperature. In both cases, the feedback mechanism works until the internal conditions return to normal, thereby maintaining homeostasis. Therefore, feedback mechanisms are essential for the maintenance of homeostasis in living organisms.(option-a)

Show the reciprocal cross: A red-eyed female (homozygous) and a white-eyed male. How many offspring will have white eyes and what is their sex?
Answers
When we see the reciprocal cross between a red-eyed female (homozygous) and a white-eyed male,we observe that none of the offspring will have white eyes. Additionally, the sex of the offspring will be half male and half female since the ratio of males to females is 1:1.
The reciprocal cross for a red-eyed female (homozygous) and a white-eyed male can be shown as follows:Female (XrXr) x Male (XwY). Females have two X chromosomes and males have an X and a Y chromosome. Red eyes are dominant to white eyes; therefore, we use Xr to represent red eyes and Xw to represent white eyes.
The offspring are as follows:All F1 females are heterozygous (XrXw).All F1 males are hemizygous (XrY).The F1 generation will have red eyes since the dominant allele is present.
None of the F1 individuals will have white eyes as the recessive allele is not present in the F1 generation.
