An activator of the enzymes present in the matrix regulating krebs cycle would
a) citrate
b) nadh
c) atp
d) succinyl coa
e) nad+

a) citrate

Explanation:

Aerobic respiration involves glycolysis and the tricarboxylic acid cycle (Krebs cycle). Pyruvate is completely degraded to carbon dioxide (CO2) and in the process, NAD is converted to NADH + H + The enzymes citrate synthase, isocitrate dehydrogenase and α-ketoglutarate dehydrogenase are the regulators of metabolic flow through the Krebs cycle and are subject to allosteric control involving NADH as inhibitor and Ca + and ADP as activators.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.

explanation:

"d.) carbon dioxide and hydrogen sulfide"
