PLEASE HELP! Describe what you know about enzymes that explains your evidence and your claim.

Biology
1 answer:
grigory [225]3 years ago
7 0

Answer:

In the case of catalase, the optimum pH is approximately pH 7.0. That is, catalase works best at a neutral pH. If the solution is too acidic (low pH value) or too basic (high pH value) the catalase is inactive and no longer functions as an enzyme.

hope this helps!!:)

What is the morphology of Homo erectus, brain size, body size, and cranial shape?​
Sedaia [141]

Answer:

Explanation:

Homo erectus existed about 200 million yeas ago as one of the early man to occupy the old world. Homo erectus are said to be the direct ancestors of other homos. The brain size of homo is population dependent and it ranges from 546–1, 251 cc (33.3–76.3 cu in). The maximum size of the brain was achieved early in their life to

this is similar to childhood in modern human.

Body size ranged widely from 146–185 cm which is about 4 feet 9 inches –6 feet 1 inch in height and 40–68 kg in weight.

Homo erectus have a flat skull that is low. The face is also flat compare to modern humans with brow ridge.

The 'G' in the universal gravitation formula
shutvik [7]

b. Gravitational constant

Explanation:

G in the universal gravitation formula represents the gravitation constant. It's value is  2.071×10⁻⁴³ s²⋅m⁻¹⋅kg⁻¹.

  • The law of universal gravitation states that "the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance separating them".

Mathematically, the law is expressed as:

            F = G\frac{m_{1} m_{2}  }{r^{2} }

Where F is the gravitational force

            G is the gravitational constant

            r is the distance

            m is the mass 1 and 2 bodies

translation can be considered to have three phases or steps: initiation, protein synthesis, and termination. Please give a detai
iVinArrow [24]

Answer and Explanation:

Prokaryotic Translation :

Initiation :

  • First amino acid participating is f-methionine.
  • Requires three initiation  components are IF_1, IF_2 and IF_3
  • Initiation complex framed at Shine-Dalgarno succession of mRNA.
  • There is no concept of Kojak rule in prokaryotic.

Protein synthesis :

  • Faster process. Adds 20 amino acids per sec.
  • mRNA is poly-cistronic.
  • Occurs on 70S ribosome.

Termination :After translation, the formyl group of first formylated methionine is removed. Methionine is retained in the polypeptide chain

Eukaryotic Translation :

Initiation :

  • First amino acid taking part in translation if methionine.
  • Requires a set of eleven initiation factors, named as eIFn.
  • Initiation complex formed at 5’ end of mRNA.
  • Kojak rule followed

Protein synthesis :

  • Slow process. Adds 1 amino acid per second.
  • mRNA is mono-cistronic.  
  • Occurs on 80S ribosome.

Termination :

Initiating methionine codon is removed from the polypeptide chain.
