Explanation Lumbricals are the fourwormlike muscles that aid in flexing the fingers at the metacarpophalangeal joints and also extend them at the interphalangeal joints. These muscles, along with the aid of the interossesousmuscles, perform the action. They are mainly used during the upstroke while writing...

Question

Chapter 9, Problem 18CYR

Summary Introduction

To review:

Whether the statement, “The lumbricals are wormlike muscles found in the hands and feet,” is true or false.

Introduction:

Many of the muscles that move the hand can be segregated into two groups, namely, the flexors and extensors. The muscles are segregated into three layers, namely, the superficial, intermediate, and deep layers. The three hand flexors that share a common tendon originate from the flexor carpi radialis, flexor carpi ulnaris, and palmaris longus.

The metabolic pathway below is used for the production of the purine nucleotides adenosine monophosphate (AMP) and guanosine monophosphate (GMP) in eukaryotic cells. Assume each arrow represents a reaction catalyzed by a different enzyme. Using the principles of feedback inhibition, propose a regulatory scheme for this pathway that ensures an adequate supply of both AMP and GMP, and prevents the buildup of Intermediates A through G when supplies of both AMP and GMP are adequate.
