Answer:
A) A single base pair change.
Explanation:
Point mutation is a change in a single base pair of a nucleotide. This comes as a results of mistakes made during DNA replication, induced by ultravoilet radiations, extreme heat and X-rays. There are three types of point or substitution mutations; change, deletion and insertion. The nucleotide bases are either mistakenly inserted, changed or deleted, thus changing the resulting protein or amino acid being coded for.
It is false that cytoplasm is a single substance like water.
It consists of 80% water, but has other elements as well.
The Cell to Mentee
A cell is the basic unit of life of a human. The body cell contains cytoplasm in which organelles are present . There is a nucleus found in eukaryotic cell. It contains the genetic material in the form of DNA with proteins and chromosomes. Inside there is nuclear membrane. Outside the nucleus, there are many other organelles like mitochondria, ribosomes, golgi apparatus, endoplasmic reticulum, and many more.
Answer:
The correct answer is C production of FAD to FADH2 by the citric acid cycle represent the energetic capacity to synthesize about 1.5 ATP.
Explanation:
Citric acid cycle is one of most important stage of cellular respiration.Citric acid cycle or TCA cycle composed of various enzyme catalyzed biochemical reaction.
various reduced coenzymes are produced during TCA cycle such as NADH,FADH2.FADH2 is formed from FAD during the conversion of succinate to fumarate.
The FADH2 then enter electron transport chain to oxidize itself into FAD along with the generation of 1.5 ATP.
