QUESTION4 The first law of thermodynamics states that: The transfer of energy from one place to another is not efficient, and some is always lost as heat. Energy present in the universe is continually being created, and can be transferred from one form to another. The amount of energy transferred from one place to another is constant and fully conserved The amount of energy present in the universe is constant, and cannot ever be created or destroyed, only transferred from one place or form to another QUESTION 5 facilitated diffusion simple diffusion vesicular transport active transport QUESTION 6 What is the hydrophilic portion of a phospholipid called? lipid phosphate fatty acid tailExplanation / Answer
Ques 4.
Answer - fourth option...because first law of thermodynamics states that energy can be tranferred from one form to another, it is never be created nor be destroyed , the energy present in the constant form.
Ques 5
Answer is second option - simple diffusion because it is easily diffuse along the concentration gradient, no protein is require for this transport.
Ques 6
Answer is second - phosphate because head part of phospholipid contain phosphate group. This head part of phospholipid is hydrophillic.
Ques 1
Answer is second - they must be non polar because plasma membrane is amphipathic (hydrophobic and hydrophillic) in nature.The red molecule in this picture are non polar. Polar molecule is not easily diffuse because phospholipid head part is polar and remaining part of phospholipid is non polar. Polar molecule is repelled by the head part of phospholipid and non polar molecule is not repelled, so it is easily diffuse. Ions can be transported by transmembrane protein.
Ques 2
Answer is third option - phosphorylation because in this process phosphate group is added to the molecule. It receive bond to the phosphate group. Best example is ATP (Adenosine tri phosphate) which is used as energy currency and it contain three phosphate group. When energy is required in the biological reaction then it donates phosphate group to this reaction. This process is known as phophorylation.
