DNA replication involves synthesis of DNA molecules, while transcription is a process that involves synthesis of RNA molecules. In both processes, DNA acts as template and provides information for synthesis of new daughter DNA or RNA strand.
The emergency department nurse should be aware that the patient is having anaphylaxis due to a<span> massive release of histamine. </span>The emergency department nurse should be aware that an apparent anaphylaxis presents as difficulty breathing, decreased SpO2, decreased blood pressure, increased heart rate, and other signs and symptoms attributed to shock. The nurse should recognize that peanuts are one of the most common allergens in triggering anaphylactic reaction.
Answer:
Photosystem I (PS-I )and photosystem II (PS-II ) are two multi-protein complexes. These complexes contain the pigments used to absorb, harvest and catalyze the photons and light energy in the photosynthetic reactions. The main purpose of photosynthesis reactions to produce high chemical energy compounds.
Photosystem I and II are different from each other because of their absorbing wavelength of light. PS-I absorbs the longer wavelength of light than PS-II.
PS-I plays the major role in the production of high energy carriers ATP and NADPH using light energy (700 nm).
PS-II plays its function in the hydrolysis of water and ATP synthesis using light energy (680 nm).
Muscle cells require more energy than most other cells in order to function. Therefore, muscle cells would be expected to have more ________ and ________ than most other animal cells.
A) Glycogen; Mitochondria B) Peroxisomes; Fat C) Mitochondria; Starch D) Ribosomes; Glycogen E) Glucose; Nuclei.
Answer:
A) Glycogen; Mitochondria
Explanation:
Glycogen is the stored form of glucose present in the animal cells. In human beings, glycogen is mainly present in muscle cells and liver cells. Breakdown of glycogen releases glucose which in turn can be fueled into cellular respiration to produce the energy required for the muscle contraction.
The aerobic phases of cellular respiration are Kreb's cycle and electron transport chain. Both of these occur in the mitochondria. Therefore, muscle cells are rich in glycogen storage and have plenty of mitochondria to ensure the supply of ATP required for their contraction. The contraction of muscles requires lots of ATP molecules as a source of energy.
D. Is the same number of adenines
Thymines and Adenines will always pair together.
