Question

You have genetically engineered a yeast cell to make a protein that will ultimately be secreted from the cell. If all is functioning well, in which order (from first to last) do you expect to find the protein in the cell until it is secreted? tER rightarrow Golgi rightarrow secretory vesicle rightarrow environment rER rightarrow Golgi rightarrow sER rightarrow nucleus rightarrow environment nucleus rightarrow rER rightarrow Golgi rightarrow secretory vesicle rightarrow environment sER rightarrow Golgi rightarrow secretory vesicle rightarrow environment rER rightarrow secretory vesicle rightarrow Golgi rightarrow environment Communication between animal cells is facilitated by light junctions. gap junctions. adhesive junctions. plasmodesmata. both choices B and C Which of the following is a phototroph? a tree a mushroom bacteria growing on decomposing matter an earthworm a person In a chemical reaction, the standard free energy change (Delta G degree) is calculated lo be 3.67 cal/mol. What can be said of the chemical reaction? The reaction is at equilibrium under standard conditions. The reaction goes spontaneously to the right under standard conditions. The reaction is not spontaneous under standard conditions. Products predominate over reactants at equilibrium under standard conditions. There can be no reaction. Which is true of heterotrophs? They capture light energy. They cannot be unicellular. They store energy in the form of heat. They can function as autotrophs in an emergency. They can obtain energy from consuming phototrophs. An enzyme

Explanation / Answer

20. C

Genitically modified dna in nucleus will pass on to rer rough endoplasmic reticulum then golgi bodies will package it and send to secretory vesicle then it will be subsiquently released into environment.

21. B

Gap junctions help to communicate between the animal cells

22. A tree

Phototropism which means movement towards light shown by plants

23. C

Gibbs energy has to be negative for a process to be spontaneous
