Question

1. Current research has shown that lysosomes carry out more tasks than was previously thought. What new roles do we now know lysosomes perform? Select the TWO answers that are correct. stimulate digestion of energy reserves under fasting conditions Ostimulate breakdown of reserves when resources are abundant stimulate cellular motility (movement) when local resources are scarce stimulate celular growth and reproduction when resources are abundant 2. How might lysosomes affect physical health? Select the TWO answers that are correct. Because lysosomes regulate lipid metabolism based on environmental cues, they might contribute to disorders such as obesity. Because lysosomes contain the genetic material of the cell, they might be a cause of deleterious mutation to DNA molecules. Because melunctioning lysosomes result in accumulation of waste products in the cell, they might affect organismallongevity Because lysosomes receive and modify proteins from the rough ER, they might be a cause of protein deficiency disorders. Identify the long-established cellular function of lysosomes. maintain cellular shape and faciate movement of the cell in the environment synthesize proteins and lipids for use in the cytosol and cellular membrane digest deteriorated cellular structures, food particles, and foreign bacteria generate celular energy by breaking down sugar in the presence of cxygen

Answer 1

1) Solution: stimulate digestion of energy reserves under fasting conditions;

stimulate cellular growth and reproduction when resources are abundant

Explanation: The current research depicts that lysosome under fasting conditions stimulate energy reserves digestion; and when there are abundant resources it stimulate growth and reproduction of cellular.

　

2) Solution: Because lysosomes regulate lipid metabolism based on environmental cues, they might contribute to disorders such as obesity;

Because malfunctioning lysosomes result in accumulation of waste products in the cell, they might affect organismal longevity

Explanation: The lysosomes can contribute to disorders such as obesity as it regulates the metabolism of lipid based on environmental cues. Moreover it can also affect organismal longevity as it causes waste products accumulation in the cell

　

3) Solution: digest deteriorated cellular structures, food particles, and foreign bacteria

Explanation: The lysosome long-established cellular function is the digestion of deteriorated cellular structures, foreign bacteria, and particles of food.
