Answer:
The correct option is option D which is 10 – 1 molecule of Oxaloacetate (OAA) is regenerated for every molecule of Acetyl-Coenzyme (AcCoA) used.
Explanation:
As the complete question is not given, the complete question is as below
Imagine that I start off with 10 molecules of oxaloacetate in a mitochondria. After running the TCA to generate 20 molecules of CO2, how many molecules of oxaloacetate will be left in the mitochondria (assuming oxaloacetate is being used only for TCA in these mitochondria)?
A) 30 – each molecule of CO2 generated corresponds to an increase of one OAA
B) 20 – every two molecules of CO2 generated corresponds to an increase of one OAA
C) 0 – two molecules of CO2 generated corresponds to one AcCoA used in the TCA; each AcCoA requires one molecule of OAA
D) 10 – one molecule of OAA is regenerated for every molecule of AcCoA used
Each cycle of TCA result in consumption of 1 Acetyl-Coenzyme (AcCoA) and 1 Oxaloacetate (OAA) molecule to give rise to 3 molecules of NADH and 2 molecules of CO2 per cycle. But at the end of each cycle, OAA molecule is regenerated. So the number of oxaloacetate(OAA) molecules remains unchanged.
Thus the correct option is option D which is 10 – 1 molecule of Oxaloacetate (OAA) is regenerated for every molecule of Acetyl-Coenzyme (AcCoA) used.
Answer:
The correct answer is - option A. differential reproductive success based on inherited traits
Explanation:
Natural selection is the differential reproductive and survival of particular population due to the difference of shared characteristics that are inherited in a specific environment. In other words natural selection is differential reproductive success based on inherited traits.
The term differential reproductive success is suggests that comparing and analyzing successful reproduction rates between groups statistically which means how many individuals of the population left behind due to not inheriting traits require for survival.
Thus, the correct answer is - option A. differential reproductive success based on inherited traits
Answer:
75%
Explanation:
3/4ths are dominant, so 75% will be red.
Answer:
Energy is passed between organisms through the food chain. Food chains start with producers. They are eaten by primary consumers which are in turn eaten by secondary consumers.
Explanation:
lysosomes and vacuoles both are cell organelles that are membrane bound, and used for storage.
lysosomes contain/ store digestive enzymes and also known as suicidal bags.
vacuoles contain/ store undigested/ waste materials
