1. Differentiate between dynamic and static equilibrium. -
./ ./ ./ ./ ./ ./ ./
correct answer Dynamic equilibrium is a position where the rate
./ ./ ./ ./ ./ ./ ./ ./ ./ ./ ./
of reactants turning into products and the rate of products turning
./ ./ ./ ./ ./ ./ ./ ./ ./ ./ ./
into reactants are similar or equal whereas static equilibrium is a
./ ./ ./ ./ ./ ./ ./ ./ ./ ./ ./
point where the reaction has come to a halt; here, the reactants no
./ ./ ./ ./ ./ ./ ./ ./ ./ ./ ./ ./ ./
longer turn into products nor the products turn into reactants.

2. Describe the relationship between response to stimuli and hom

eostasis. - ./
correct answer Your body responds to stimuli (heat, light, etc.) to
./ ./ ./ ./ ./ ./ ./ ./ ./ ./ ./ .
maintain homeostasis. When stimuli interrupts homeostasis, posi

tive or negative feedback occur to restore equilibrium throughout
./ ./ ./ ./ ./ ./ ./ ./ ./
the body. ./
3. Differentiate between positive and negative feedback loops. In

./ ./ ./ ./ ./
correct answer Positive feedback loops amplify the initiating sti

negative feedback loops counteract the changes of the system, ma

5. Summarize the role of enzymes in the regulation of homeostasi
./ ./ ./ ./ ./ ./ ./ ./ ./ ./
s. - ./
correct answer Enzymes act as catalysts that speedup the process
./ ./ ./ ./ ./ ./ ./ ./ ./ ./ ./
of regulating homeostasis. The activity of the particular enzyme (
./ ./ ./ ./ ./ ./ ./ ./ ./
typically a protein) can be regulated and the final product that is
./ ./ ./ ./ ./ ./ ./ ./ ./ ./ ./ ./
made control the rest of the process.

6. Summarize the role of cellular transport in the regulation of ho

meostasis. - ./
correct answer Transport (can be passive or active) helps regulat
./ ./ ./ ./ ./ ./ ./ ./ ./ ./
e homeostasis by sending signals and transporting mechanisms.

of a substance transported of each. - correct answer Passive:
