Answer:

1-4-2-3-5

Explanation:

The PDHC is made up of multiple copies of 3 different enzymes: pyruvate dehydrogenase (PDH, E1: 20-30 copies), dihydrolipoamide S-acetyltransferase (DLAT, E2: 60 copies) and dehydrogenase dihydrolipoamide, (DLD, E3: 6 copies). The complex also requires five different coenzymes: CoA, NAD +, FAD +, lipoic, and thiamine pyrophosphate (TPP). Three of the complex coenzymes are closely linked to the complex enzymes (TPP, lipoic acid, and FAD +) and two are used as carriers of the products of PDHC activity (CoA and NAD +). The pathway for oxidation of PDH from pyruvate to acetyl-CoA is a diagram below.

Answer:

The correct answer is break down of pyruvate

Explanation:

Krebs cycle is one of the most significant process of aerobic respiration.During krebs cycle pyruvate is broken down to acetyl CoA which interacts with oxaloacetate to form the first metabolite of Krebs cycle known as citrate which contain 3 -COOH group That"s why krebs cycle is also termed as Tricarboxylic acid cycle.

Which law might require you to do some math calculations?
Vadim26 [7]

Answer:

Law 2

Explanation:

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

Hence, Law 2 might require you to do some math calculations.

For example, an object having a mass of 20kg is pushed by John and it then accelerates down the inclined plane at a rate of 0.5m/s². Find the force applied on the object.

Given the following data;

Mass = 20kg

Acceleration = 0.5m/s²

To find the force;

Force = mass * acceleration

Substituting into the equation, we have;

Force = 20 * 0.5

Force = 10 Newton.

The ant, the spider and the beetle are secondary consumers?
brilliants [131]
Insects are very common not only in today's world but also in ancient days. It is also estimated that the population of insect are 10 times more than thehuman beings. It is little bloodcurdling to hear but it is the fact. They are found in all parts of the world even in the ocean. Insects are astonishing creatures it is quite interesting to learn about them. Insects are very advantageous to man and his environment.

Insects are small species that is characteristic as an air breathing animal with a hard jointed exoskeleton. The whole body of the insects is divided into three parts: The head, thorax, and the abdomen.

Insects are classified into different known species in the world but still some new species are being discovered. The known species can be classified into 32 orders with 125 different families and about 500,000 species. Among them the Beetles are the largest group. Insects act as the varied group in the animal world.

Many insects act as the primary consumers for other animals since they are herbivores. These insects are rich in protein and energy which they provide to the secondary consumers also known as carnivores. Spiders, wireworms etc, act as the secondary consumers which cannot survive without depending on the primary consumers. Both the primary and secondary act as the prey to the tertiary consumers.

Insects help with a lot of important functions in our ecosystem. Mainly they help in decomposition of the waste products and pollination. These two acts of the insects led a greener environment. Decomposition of dead and waste materials provides more nutrients to the soil thus helping the soil to regain its health. Bugs such as ants, beetles burrow the soil to provide channels for water and air ventilation to the soil. Bees help in pollution thus helping in plantation. Bugs help the gardeners by preventing the plants from aphids and caterpillars. So without insects the world would not have see a fast growth that the way it is today.

Insects are exceedingly a diverse type of animal. The structure of the insects varies greatly with the different types of species. But the basic anatomy of the insect is the same. All the insects have an external exoskeleton and the body is divided into three major segments: head, thorax, and abdomen
