1. How is it possible for a phospholipid to be hydrophilic and hydrophobic? (2) 1

Biology
1 answer:
swat322 years ago
8 0
Phospholipids consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic.

What evidence best supports the conversation during photosynthesis?
lions [1.4K]

The evidence that best supports conversation during photosynthesis is: Light energy is converted to chemical energy during photosynthesis ( A )

Photosynthesis is the process whereby plants make use of water and carbon dioxide found in the atmosphere to transform/convert the light energy from the sun into chemical energy.in the process of synthesizing food  

The products of photosynthesis include oxygen and glucose while the conversion during photosynthesis takes place when the chloroplast absorbs the light energy from the sunlight and converts it another form of energy ( chemical energy ).

Hence we can conclude that The evidence that best supports conversation during photosynthesis is ; Light energy is converted to chemical energy during photosynthesis.

Dab most likely inhibits which reaction?a. phosphorylation of glucose. phosphorolysis of glycogen. export of lactate from cellsd
Pie

Dab most likely inhibits phosphorolysis of glycogen reaction.

<h3>What is phosphorolysis?</h3>
  • Inorganic phosphate acts as the attacking group during phosphorolysis, which is the cleavage of a molecule.
  • It's comparable to hydrolysis.
  • A reversible process akin to hydrolysis where phosphoric acid behaves like water and produces phosphate as a byproduct.
  • It's comparable to hydrolysis.
  • Glycogen phosphorylase, which catalyzes the assault of inorganic phosphate on the terminal glycosyl residue at the nonreducing end of a glycogen molecule, is an example of this.
  • The difference is that while reactions involving hydrolysis use water to split larger molecules into smaller ones, reactions involving phosphorolysis use phosphate to achieve the same result.
  • The primary enzyme in utilizing the glycogen reserves in the muscle and liver is known as glycogen phosphorylase.
  • It catalyzes the sequential phosphorolysis of glycogen to liberate glucose-1-phosphate.

Summarize how the climate of the Miocene epoch impacted the evolution of hominins
andrezito [222]

Answer with Explanation:

The Miocene epoch was deeply characterized by<em> seasonal conditions</em>, such as having more colder winters in the northern areas.

In the <em>late Miocene</em>,<u> open vegetation system expanded. </u>These included<em> grasslands, woodlands and shrublands.</em> As a result, more primates inhabited the area. Several habitats became diverse from each other, thus allowing the species to adapt, including their locomotion. For example, the species who used to live on trees, turn towards living on land (terrestrial life). Certain animals also came about such as <em>pigs, giraffes, monkeys, etc.</em> Scavenging hominins also scattered. When it comes to hominins, a major type of locomotion evolved called "bipedalism." <u>This allowed the hominins to walk using the lower limbs (two feet).</u>

During elongation, RNA polymerase has three prominent channels, or grooves. These channels provide sites for all of the followin
kirill [66]

Answer:

<h2>A site for the exit of the diphosphates removed from the nucleotide triphosphates.</h2>

Explanation:

Transcription occurs in three steps, i) initiation, ii) elongation, and iii) termination.

Elongation: during elongation , the RNA polymerase add new nucleotides in the growing chain of RNA molecule until it encounter terminator factor, or until it terminate transcription.  RNA polymerase has three prominent channels, i) channel for entry of DNA template strand, ii) channel for exit of DNA strand  and iii) channel for exit of newly synthesized RNA molecule. There are lots of other enzymes which helps in transcription.
