DNA replication takes place during:

Portion of an enzyme to which a substrate can attach

netineya [11]

Answer:

An active site

Explanation:

Enzymes are biological catalysts that catalyze chemical reactions or biochemical reactions. They are substrate specific and each enzyme acts on a certain specific substrate.
Enzymes contain a pocket-like structure called the active site where the substrate binds according to the induced-fit model.
Upon binding of the substrate to the active site catalysis takes place and the substrate is converted to product. Enzymes remain unchanged after the reaction.

most biological macromolecules contains carbon, hydrogen and oxygen atoms. which of these has the carbon, hydrogen and oxygen in

nata0808 [166]

The answer would be A. carbohydrates (carbs) because carbs are generally composed of sugars and glucose (as an example) has the ratio between carbon, hydrogen and oxygen in a 1:2:1 ratio in its form: C6H12O6

Under which conditions do most types of cells function at optimal levels

Scrat [10]

Explanation:

Cells maintain a constant internal environment; this process called homeostasis, ensures that cells obtain an optimal environment in which they can best function.

The endocrine system involves chemical signalling via the secretion of molecules called hormones into extracellular fluid. They bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis.

It includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions. The bone, adipose tissue, heart, pancreas and liver are a few of the regions of the body which show endocrine function. The brain, or control center functions to receive and process the information from the receptor. Effectors receive the control center's command and illicits a response in the form of a feedback loop, that may oppose or enhance the stimulus.

Further Explanation:

During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis. Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

For example, cells within the human body function at an optimal temperature between 97°F (36.1°C) and 99°F (37.2°C). This is due to the optimal temperature requirement of the enzymes within the human body, which requires this specific range to obtain activation energy.
