How can amino acids be enabled as buffers in biological tissue?

1 answer:

6 0

Amino acids form Zwitterions which means that the -NH₂ group becomes -NH₃⁺ that will remove alkali OH⁻⁻ ions to form water and -NH₂

The -COOH becomes a -COO⁻ which reacts with acidic H⁺ ions to reform the -COOH group.

Because of this fact and the fact that the zwitterions can be in equilibrium means that it can act as a pH buffer in tissue as the body contains many amino acids.

Hope that helps :)

lara [203]

With the rain forests disappearing rapidly, it is believed that many thousands of biological species will lose their habitats and will not survive. In addition since rainforests are responsible for regulating the global carbon dioxide concentration, it is likely that rain forest loss will impact the Earth's climate.

A skeletal muscle is a composition of several components bundled one into the other. at which structural level in the muscle doe

Alexandra [31]

The structural level in which the muscle produces the contraction is known as the muscle fiber.

<h3>What is a muscle fiber?</h3>

A muscle fiber is a single muscular cell that is able to contract by using specialized proteins such as filaments of myosin and actin.

This unit (muscle fiber) is able to contract both in vivo and in vitro by establishing suitable environmental conditions (e.g., proper calcium levels).

In conclusion, the structural level in which the muscle contracts is the muscle fiber.

Molecular evidence has led taxonomists to group bilaterally symmetrical animals in one of three clades: Deuterostomia, Lophototr

Likurg_2 [28]

Answer:

One distinguishing characteristicof all three clades i.e Deuterostomia, Lophototrochozoa, or Ecydysozoa are balstopore development, internal body cavity and exoskeleton respectively

Explanation:

Apart from molecular difference, there exist structural differences between the three clades, which are as follows –

Deuterostomia – The development of embryo is different from the protostomes as the first opening in this clade is anus and the blastopores develops into the anus.

Lophototrochozoa – They do not have ant distinguished internal body cavity. Organs with in coelom can move freely. For example - flatworm

Ecydysozoa – have the ability to shed their tough and flexible exoskeleton i.e cuticle , several times throughout their life span
