Answer: D. some components of the cycle are used as building blocks for certain anabolic pathways.
Explanation:
The citric acid cycle or Kreb's cycle is the part of the cellular respiration. It is a sequence of chemical reaction which is used by all the aerobic organisms so as to store energy by the process of acetyl CoA oxidation derived by the process of fats, proteins and carbohydrates into forms like carbon dioxide and adenosine triphosphate (ATP).
The acetyl CoA is used in the process of synthesis of fatty acids. The citrate is used for the synthesis of cholestrol. The oxaloacetate and alpha ketogluterate are used for the synthesis of aminoacids. Succinyl CoA is used for the synthesis of poryphrins and fatty acids.
Answer:
It is similar because the nuclear envelope is a membrane similar to the cell membrane around the whole cell. There are pores and spaces for RNA and proteins to pass through while the nuclear envelope keeps all of the chromatin and nucleolus inside. When the cell is in a resting state there is something called chromatin in the nucleus.
Explanation:
Starch cannot diffuse across the membrane because starch molecules are too large to fit through the pores in the dialysis tubing, whereas iodine is a smaller molecule and therefore can diffuse across.
Answer:
DNA is made up of molecules called nucleotides each nucleotides contains a phosphate group a sugar group and nitrogen base
Correct Question:
An asynchronous counter signal:
Answer:
overrides the clock-gated input signal(s).
Explanation:
An asynchronous counter signal normally overrides the clock-gated input signal(s).
An asynchronous counter is a type of counter whereby each flip-flop output serves as the clock input signal for the next flip-flop signals and preset can be used to override the clock-gated input signal(s).
