Question
1/Name the key enzyme in the photorespiration of plants 2/ biological membranes are effective insulators preventingingress and egress of cytoplasmic solutes. How, then, do cellsacquire solutes? 3/ Name the transporter that is the principal source of theenergy gradient that co-transporters use to move solutes into orout of the plant cell. 4/Fritz Went developed the bioassay. Explain what a bioassayaims to do. 5/ define an auxin. Are auxins related by chemical structureor by another feature? 6/ How are the actions of auxin and gibberellin at the levelof the gene fundamentally similar? 7/ what is expansin and how does it affect plant growth. Does"growth" of the wall require a living protoplast? 1/Name the key enzyme in the photorespiration of plants 2/ biological membranes are effective insulators preventingingress and egress of cytoplasmic solutes.

Does"growth" of the wall require a living protoplast?Explanation / Answer
1. Rubisco is the key enzyme and is actually the most abundantenzyme on the planet. 2. Cells acquire solutes through a bunch of different mechanisms,including facilitated diffusion and active transport. 3. ABC (ATP bonding cassette) is the transporter. 4. Bioassays, such as ELISA, are used to detect an antibody orantigen. 5. Auxins are a type of growth hormone in plants including IAA.Most auxins have benzen rings in their structure. 6.Gibberellin stimulates cell division and elongation, while auxinstimulates only cell elongation. 7. Expansion is growth, and yes the wall require protoplast toexpand.
