Middle lamella Plant cells are connected to each other via ______ which is analogous to __________ in animal cells Plasmodesmata Gap junctions The ATP produced in chloroplasts are used In the dark reactions of photosynthesis to power the Calvin cycle thus sy...

How are polymers formed and broken? formed via dehydration(condensation) and broken due to hydration (hydrolysis dissolution of glycosidic bond) important amino acids glycine= R=H very flexible proline= fixed, and very rigid R=secondary amino loop, prevent amino acid from alpha helices cystine= can form disulfide bridges methionine= also contains sulfur and is the start codon AUG

Transformation Integration of a foreign chromosome fragment (plasmid) into the host genome Gametic Isolation When two closely related species share the same habitat, but the sperm of one species cannot fertilize the egg of the other species, and vice versa. Pancreas Enzymes Carboxypeptidase, chymotrypsin, lipase, and trypsin Mineralcorticoids Promote the retention of water, sometimes through the retention of minerals. i.e Aldosterone, which promotes the retention of sodium
