Answer:
depolarization leading to action potentials
Explanation:
The voltage-gated Na+ channels are responsible for rapid depolarization phase of the action potential. Action potential generation require depolarization of neuronal membrane which is acquired by influx of sodium ions through voltage gated sodium ion channels. If the Na+ channels are blocked, there will be no influx of sodium ions to cause depolarization hence action potential will not be generated.
Answer:
C
Explanation:
enzymes are catalytic protein that speed up reactions in the body
Answer:
b) golgi apparatus contains powerful oxidative enzymes and also package cell products
Explanation:
The Golgi apparatus is a cellular organelle responsible for protein modification, package, and transport. The organelle is made up of a series of flattened sacs. These sacs bud off into vesicles. The Golgi packages the proteins into vesicles so that they can be transported to their destination.
The peroxisome contains powerful oxidative enzymes, responsible for breaking down lipids.
The process of creating egg cells.
Answer:
Matrix, Mitochondrion, Kreb's cycle, Pyruvic acid
Explanation:
The above question illustrates aerobic cellular respiration, specifically the second stage called Kreb's cycle or Citric acid cycle. This process occurs in the inner membrane of the mitochondrion of eukaryotic cells called MATRIX.
It occurs when the pyruvic acid produced during Glycolysis (first stage of cellular respiration that occurs in the cytoplasm) is converted to Acetyl CoA in order to enter the citric acid cycle in the mitochondrion. The Acetyl CoA is then used in a series of reactions that comprises of reduction-oxidation, hydration, dehydration, and decarboxylation.
This reactions involving 8 steps converts the Acetyl CoA (from pyruvic acid) to 2 molecules of CO2, 1 molecule of GTP/ATP, and electron donors NADH2 and FADH2.
