Q

Active Site

Where is it and what happens here?

A

The active site is the specific loaction where a substrate attaches

Must be a lock and key to work properly.

Inhibitor or cofactors can change the shape or block the active site from binding to the substrate.

Glucose

Photosynethis or cellular respiration? What is it? Chemical forumla?

A

The main sugar found in your blood. It is your body’s primary source of energy. It comes from the food you eat. Your body breaks down most of that food into glucose and releases it into your bloodstream. When your blood glucose goes up, it signals your pancreas to release insulin.

C6H12O6

Negative Feedback

What does it do and give an example

A

Reactions to return something back to its set point to maintain homeostatsis. EX: Body Temperature regulation with sweating and shivering.

A cycle of starting with a stimulus then a signal sendt then a response and then the stimulus is either decreased or increased to return to normal.

48
Q

Positive Feedback

What does it do and give an example.

A

Positive feedback cause amplifcation. EX: when apples rippen it realases ethylene causes more apples to rippen.

A cycle that starts with by being at normal and then a stimulus is activated and a single is sent and the response acts and a new stimulus and so on.
