What enzyme is kept in its active form by the presence of vitamin C in the diet? Is prolyl hydroxylase the active form enzyme here?

Answers

Answer 1
Answer: yes, Porlyl Hydroxylase

Enzyme productions also depend on the supply of iron and it is crucial in the total development of children who are growing and developing hormones, neurotransmitters, and new cells within their body. If iron stores are low, memory, mood, attention span, and focus are among the effects of the deficiency because oxygen transport in the blood is lessened or diminished.

The law of conservation of momentum states that the total momentum of a system _____.-increases
-decreases
-remains constant

Answers

The law of conservation of momentum states that the total momentum of a group of objects does not change unless outside forces act on the objects.

The correct answer is remains constant.

The law of conservation of momentum can be stated as in an isolated system  when any collision between two bodies takes place then the the total momentum remains constant. This law has been derived from the Newton's law of motion. The collision of body transfers its energy from body A to another body B.

Hence, in this way the total momentum remains constant.

Radiocarbon dating would be useful in dating the age of Earth.
True or False

Answers

The given statement is False.

Radiocarbon dating cannot be used determine the age of the earth because the earth is million years old.

Radiocarbon dating can be used only for the substance that is 100-40,000 years old.

As, the earth is older than 40,000 years of age radiocarbon dating cannot be used for substances that is this much old.

Which homeostatic process requires energy to move particles across the plasma membrane?1.active transport
2.passive transport
3.dynamic equilibrium
4.osmosis

Answers

The right answer is 1. active transport.


Active transport refers to the passage of an ion or molecule across a membrane against its concentration gradient.

If the process uses chemical energy produced, for example, by the hydrolysis of a nucleotide triphosphate such as adenosine triphosphate, it is called primary active transport.

Active transport is opposed to passive transport, which does not use energy.

Active transport is the homeostatic process that requires energy to move particles across the plasma membrane.

Further Explanation

Transport in living organisms

  • Plants and animals use various processes to transport materials from one point to another.
  • There are classified as either passive transport or active transport.

Active transport  

  • It is a type of transport in living organisms that involves movement of substances against a concentration gradient through the plasma membrane.
  • It  involves use of energy in form of ATP to aid transport of substances.

Passive transport

  • It is a type of transport that does not involve the use of energy to aid movement of substances in living organisms.
  • Passive transport involves free movement of substances and through special types of transporters or carriers.
  • Types of passive transport includes; simple diffusion, facilitated diffusion, osmosis, and mass flow among others.

Types of passive transport

Facilitated diffusion

  • Facilitated diffusion is a type of passive transport which involves the diffusion of solutes by use of transport proteins in the plasma membrane.
  • Facilitated diffusion uses transport proteins to transport solutes down their concentration gradient.

Osmosis  

  • Osmosis is a special diffusion that involves the movement of water molecules from a region where they are highly concentrated to a region where they are lowly concentrated through a semipermeable membrane.
  • It may also refer to the movement of water molecules from a region of low particle concentration to a region of a high particle concentration.

Diffusion  

  • Diffusion is a type of passive transport that involves movement of particles from a region of high concentration to a region of low concentration.
  • Diffusion involves movement of molecules of substances other than water.
