activator
(noun)
any chemical or agent which regulates one or more genes by increasing the rate of transcription
Examples of activator in the following topics:
-
Activities of the Business: Financing, Investing, and Operating
- Activities of the business include operating activities and non-operating activities such as investing activities, and financing activities.
- Activities of the business include operating activities, investing activities, and financing activities .
- Operating activities, or the fundamental activities the business engages in can include the production, sales, and delivery of the company's product as well as collecting payment from its customers.
- In addition to operating activities businesses engage in non-operating activities.
- Other activities which impact the long-term liabilities and equity of the company are also listed in the financing activities.
-
Reporting Financing Activities
- Reporting financing activities involves determining if cash is received or paid out due to financing activities such as issuing stock or paying dividends.
- Other activities which impact the long-term liabilities and equity of the company are also listed in the financing activities section of the cash flow statement.
- Everything concerning the loan is a financing activity.
- Extending credit is an investing activity, so all cash flows related to that loan fall under cash flows from investing activities, not financing activities.
- Non-cash financing activities may include:
-
Activity Theory
- The activity theory of aging proposes that older adults are happiest when they stay active and maintain social interactions.
- The theory assumes a positive relationship between activity and life satisfaction.
- However, critics of activity theory state that it overlooks inequalities in health and economics that hinders the ability for older people to engage in such activities.
- Participating in activities from which they used to derive pleasure in the past, such as singing, helps older people stay active and engaged.
- Compare the activity model and disengagement model of aging, in terms of activity level and level of life satisfaction
-
Components of the Statement of Cash Flows
- The cash flow statement has 3 parts: operating, investing, and financing activities.
- There can also be a disclosure of non-cash activities.
- Other activities that impact the long-term liabilities and equity of the company are also listed in the financing activities section of the cash flow statement.
- Statement of cash flows includes cash flows from operating, financing and investing activities.
- Recognize how operating, investing and financing activities influence the statement of cash flows
-
Plasma Membrane Hormone Receptors
- Binding of these hormones to a cell surface receptor results in activation of a signaling pathway; this triggers intracellular activity to carry out the specific effects associated with the hormone.
- The activated G protein in turn activates a membrane-bound enzyme called adenylyl cyclase.
- These activated molecules can then mediate changes in cellular processes.
- The binding of a hormone at a single receptor causes the activation of many G-proteins, which activates adenylyl cyclase.
- Hormone binding to receptor activates a G protein, which in turn activates adenylyl cyclase, converting ATP to cAMP. cAMP is a second messenger that mediates a cell-specific response.
-
Cash Flow from Investing
- These activities are represented in the investing income part of the income statement.
- However, this cash flow is not representative of an investing activity on the part of the company.
- The investing activity was undertaken by the shareholder.
- Therefore, paying out a dividend is a financing activity.
- Some examples of investment activity from the company's perspective would include:
-
Enzyme Catalysis
- Enzymes are proteins that accelerate biochemical transformations by lowering the activation energy of reactions.
- Enzymes are proteins that are able to lower the activation energy for various biochemical reactions.
- At the active site, the substrate(s) can form an activated complex at lower energy.
- This change stabilizes the transition state complex, and thus lowers the activation energy.
- An enzyme catalyzes a biochemical reaction by binding a substrate at the active site.
-
Cash Flow from Financing
- Cash flows from financing activities arise from the borrowing, repaying, or raising of money.
- Everything concerning the loan is a financing activity.
- Extending credit is an investing activity, so all cash flows related to that loan fall under cash flows from investing activities, not financing activities.
- As is the case with operating and investing activities, not all financing activities impact the cash flow statement -- only those that involve the exchange of cash do.
- Distinguish financing activities that affect a company's cash flow statement from all of the business's other transactions
-
Avoiding Passive Voice
- A way to focus your sentences on action and actors is to use the active voice rather than the passive voice.
- Research shows that readers comprehend active sentences more rapidly than passive ones.
- The active voice also eliminates the vagueness and ambiguity that often characterize the passive voice.
- The active voice keeps the focus of the sentence on the action.
- A memo written in the active voice will have a greater impact than one written in the passive voice.
-
Secondary Active Transport
- In secondary active transport, a molecule is moved down its electrochemical gradient as another is moved up its concentration gradient.
- Unlike in primary active transport, in secondary active transport, ATP is not directly coupled to the molecule of interest.
- Both antiporters and symporters are used in secondary active transport.
- Secondary active transport brings sodium ions, and possibly other compounds, into the cell.
- An electrochemical gradient, created by primary active transport, can move other substances against their concentration gradients, a process called co-transport or secondary active transport.
