Answer:
Dissociation of the myosin head from the actin filament requires the binding of ATP (I).
Answer:
<em>Clostridium perfringens</em>
Explanation:
<em>Clostridium perfringens</em> is a bacterium characterized by being a large, gram-positive, boxcar-shaped bacillus.
It is part of the facultative aerobic bacteria group (they can survive both in the presence or absence of oxygen) and is also a spore-forming bacterium (spores are small structures capable of generating new bacteria).
<em>Clostridium perfringens</em> can cause food poisoning, which results from the ingestion of contaminated food (usually meat and animal products) by the bacteria.
Once in the small intestine, the bacteria releases the toxin that usually causes diarrhea.
Answer: Your answer is True.
Explanation:
Answer:
<h2> They contain an enzyme activity that acts on a cytosolic substrate.</h2>
Explanation:
Receptor enzyme have three domains, i) extracellular domain, ii) trans-membrane domain and iii) cytosolic domain.
They contain an enzyme activity that acts on a cytosolic substrate side.
They contain one of the following function:
Tyrosine kinase activity, tyrosine phosphatase activity, serine or threonine kinase activity, and guanylyl cyclase activity.
Answer:
Water follows the sugar molecules into the sieve elements through osmosis (since water passively diffuses into regions of higher solute concentration). This water creates turgor pressure in the sieve elements, which forces the sugars and fluids down the phloem tubes toward the sinks.
