Explanation

Saturation occurs when all active sites of the enzyme molecules are fully occupied by the substrate.

At this point, adding more substrate doesn't increase the reaction rate, as the enzyme is working at its maximum capacity (Vmax).

Explanation

Tertiary structure refers to the 3D folding of a protein, stabilized by interactions like disulphide bonds, hydrogen bonds, and hydrophobic interactions.

Disulphide (S-S) linkages are covalent bonds formed between cysteine residues, specifically contributing to the protein's tertiary structure stability.

Explanation

 The symptoms of numbness, tingling, weakness, or burning sensation and painful movement of the arms or legs are most likely indicative of  Spinal Injuries. 

These symptoms are classic signs of nerve damage, which can occur due to a spinal cord injury affecting the nerves that transmit sensation to the arms and legs

Explanation

HbA1c reflects long-term blood glucose levels.

Biguanides, such as Metformin, are commonly used to treat type 2 diabetes to help decrease HbA1c.

HbA1c lowering effect

1. Metformin: Typically reduces HbA1c by 1-2% (11-22 mmol/mol).

2. Sulfonylureas: May reduce HbA1c by 0.5-1.5% (5.5-16.5 mmol/mol).

3. Acarbose: Typically reduces HbA1c by 0.5-1% (5.5-11 mmol/mol).

Explanation

Professional training is education focused on developing specific skills for a career.

Professional training involves:

• Skill Enhancement
• Knowledge Update
• Career Development
• Compliance
• Productivity Boost
• Problem-Solving

Explanation

A place that does not have safe oxygen levels is typically referred to as a "Confined Space."

Where serious injury can occur from hazardous substances or conditions within the space or nearby (e.g. lack of oxygen)

There are two types of confined spaces

• Permit
• Not-Permit

Explanation

• Mitosis is a process of cell division that results in the production of two daughter cells, each with the same number of chromosomes as the parent cell.
• This process is essential for growth, repair, and asexual reproduction in living organisms.

Explanation

• The Forebrain is the largest part of the brain and comprises two hemispheres: the left hemisphere and the right hemisphere. 
• The forebrain includes the cerebrum, which is responsible for processing sensory information, controlling movement, and managing higher-level cognitive functions such as thought, emotion, and memory.

Explanation

The brain is divided into three primary parts:

• Forebrain (includes the cerebrum, thalamus, and hypothalamus)
• Midbrain (connects the forebrain to the hindbrain, and regulates auditory and visual processing)
• Hindbrain (includes the cerebellum, pons, and medulla oblongata, and regulates movement, balance, and basic bodily functions)

Explanation

Tundra is a region with a very cold climate, found in the Arctic and Antarctic regions, characterized by:

• Low temperatures
• Short growing season
• Limited vegetation (mainly low-growing shrubs, grasses, and mosses)
• Permafrost (frozen soil)
