Answer:
Genomic Instability
Explanation:
Normal cells have normal DNA and a normal number of chromosomes. Cancer cells often have an abnormal number of chromosomes and the DNA becomes increasingly abnormal as it develops a multitude of mutations.In contrast to normal cells, cancer cells don't stop growing and dividing, this uncontrolled cell growth results in the formation of a tumor. Cancer cells have more genetic changes compared to normal cells, however not all changes cause cancer, they may be a result of it.
Answer:
E1: Pyruvate dehydrogenase, TPP, oxidative decarboxylation reaction
E2: Dihydrolipoyl transacetylase, Lipoamide and Co-enzyme A, transacetylation reaction.
E3: Dihydrolipoyl dehydrogenase, FAD and NAD+, oxidation reaction
Explanation:
Pyruvate dehydrogenase is a multi-enzyme complex with 5 co-enzymes and 3 apo-enzymes:
Pyruvate dehydrogenase (E1) , which uses thiamine pyrophosphate (TPP) as as co-enzymes to catalyze oxidative decarboxylation of pyruvate to hydroxyethyl-TPP.
Dihydrolipoyl transacetylase (E2): which uses lipoamide and coenzyme A as co-enzymes to catalyse the transacetylation from TPP to Lipoamide to form acetyl lipoamide.
Dihydrolipoyl dehydrogenase (E3) which uses FAD and NAD+ as co-enzymes to catalyze the oxidation of lipoamide
Answer:
C
Explanation:
The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A. So the full sequence of events is as follows: Layer C formed.
Tropical climate is a region of the earth surrounding the equator. When the earth is exposed to light from the sun it is right over the equator and up 23 degrees of latitude Tropic of Cancer in the northern hemisphere and Tropic of Capricorn in the southern hemisphere
