Understanding Ageing and Longevity

What is the main focus of scientists in the field of ageing research?

• To find ways to slow down or reverse ageing

• To develop new types of canes for the elderly

• To create more effective glasses and dentures

• To study the effects of chronic back pain

What role do free radicals play in the ageing process?

• They prevent the accumulation of errors in proteins

• They are highly reactive chemicals that can damage proteins and DNA

• They increase the number of new cells

• They help repair damaged DNA

Why is it challenging to use stem cells to combat ageing?

• Stem cells require a specific environment to survive

• Stem cells are too expensive to produce

• Stem cells cannot divide

• Stem cells are only found in the brain

What is the balance between anabolism and catabolism in a cell?

• The balance between DNA repair and protein synthesis

• The balance between building up and breaking down processes

• The balance between energy production and energy consumption

• The balance between cell growth and cell death

What is the role of signalling pathways in cellular metabolism?

• They eliminate free radicals

• They prevent cells from dividing

• They communicate changes in nutrition and energy levels to the cell

• They help cells grow larger

How does metformin potentially affect longevity?

• By increasing the number of stem cells

• By altering proteins and affecting metabolic pathways

• By reducing the need for calorie restriction

• By eliminating the need for exercise

What is a common strategy mentioned for delaying the onset of age?

• Increasing calorie intake

• Calorie restriction

• Avoiding all forms of exercise

• Taking daily naps

What is the potential benefit of rapamycin according to the research?

• It can increase lifespan and might help treat cancer

• It can cure diabetes

• It can prevent all forms of stress

• It can eliminate the need for glasses

What is the significance of studying centenarians in ageing research?

• To learn about their childhood experiences

• To determine their favorite hobbies

• To understand common habits and genes that contribute to longevity

• To find out their favorite foods

What is a potential downside of using drugs like metformin for longevity?

• They are too expensive

• They have been found to alter many proteins, and their full effects are unknown

• They require a specific diet to work

• They are only effective in mice
